@weisJ
when will this problem be solved?

weisJ · 2020-06-02T17:41:50Z

@Ilolka1337 I have still yet to reproduce the issue. As I have already mentioned until then there is nothing I can do really. Have you already tried version 2.1.1?

Ilolka1337 · 2020-06-05T05:39:04Z

@weisJ
2.2.1-SNAP | tests
https://mega.nz/file/2vIixKKD#x4uhS7S8aQg1NTx7TGLNGUL_aoPOVlIRYC5VPa8I0OQ

weisJ · 2020-06-05T07:27:44Z

Are you building with the newest native binaries?

Ilolka1337 · 2020-06-07T06:00:02Z

@weisJ
I download from there https://github.com/weisJ/darklaf/actions/runs/121880047
I now have little disk space to store visual studio

weisJ · 2020-06-07T21:53:08Z

Don't worry you won't need visual studio. I was just making sure you are using the latest binaries.

Are you facing the same problems when opening the popup of a JMenuBar?
Also could you try with the following line after installing the laf?

LafManager.install();
JPopupMenu.setDefaultLightWeightPopupEnabled(true);

What happens if you set your display scale to 100%?

No need for the video. Could you please answer the remaining two questions?

I did not notice a problem with this

What happens if you set your display scale to 100%?

also found no problems

Ilolka1337 · 2020-06-08T08:54:50Z

@weisJ
what was the problem really?

weisJ · 2020-06-08T09:23:07Z

It seems to be a combination of the heavy weight popup and the display scaling. Although it’s a bit strange that only the combobox popup is affected.

Could you check if using the system laf together with

JPopupMenu.setDefaultLightWeightPopupEnabled(false);

produce the issue?

Ilolka1337 · 2020-06-08T09:47:44Z

@weisJ
only works if I set true in this parameter

Ilolka1337 · 2020-06-08T09:51:16Z

Ilolka1337 · 2020-06-08T10:01:20Z

@weisJ
if there are any other problems, I will write to you

weisJ · 2020-06-08T10:25:35Z

@weisJ
only works if I set true in this parameter

What I want you to check is whether using the System LookAndFeel instead of darklaf produces the issue.

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
JPopupMenu.setDefaultLightWeightPopupEnabled(false);

Even though

JPopupMenu.setDefaultLightWeightPopupEnabled(true);

fixes the issue this isn't the way darklaf is intended to look. This way popups loose their shadow and the edges of the popup may be hard to spot.

@weisJ
in new updates the same problems again

Ilolka1337 · 2020-07-11T14:21:30Z

@weisJ only now it is not fixed using JPopupMenu

weisJ · 2020-07-11T14:56:56Z

@weisJ
in new updates the same problems again

Does this mean the problem went away in some intermediate versions?
If not I'll have to say that I never claimed this issue has been resolved and saying that the issue is still
present doesn't add anything to the conversation.

@weisJ only now it is not fixed using JPopupMenu

This honestly reflects more what I am imagining would happen anyway. Good to know the issue
is more consistent now.

Does

LafManager.install();
JPopupMenu.setDefaultLightWeightPopupEnabled(true);

still solve the issue?

Ilolka1337 · 2020-07-11T16:40:07Z

@weisJ
this problem was fixed in only one version; in new versions the problem appeared again only now it cannot be fixed with JPopupMenu.setDefaultLightWeightPopupEnabled (true);

weisJ · 2020-07-11T22:17:22Z

@weisJ
this problem was fixed in only one version;

By fixed do you mean the issue wasn't present or it could be circumvented by using JPopupMenu.setDefaultLightWeightPopupEnabled (true);? Also which version?

in new versions the problem appeared again only now it cannot be fixed with JPopupMenu.setDefaultLightWeightPopupEnabled (true);

Could you provide sample code to reproduce the issue? Preferably for the popup menu case.

Ilolka1337 · 2020-07-21T19:26:48Z

By fixed do you mean the issue wasn't present or it could be circumvented by using JPopupMenu.setDefaultLightWeightPopupEnabled (true);? Also which version?

it was fixed in one of the versions but I decided to install each new one so I don't remember the exact version
now JPopupMenu.setDefaultLightWeightPopupEnabled (true); no longer works as a solution to the problem, I don't know what to do

weisJ · 2020-07-22T11:05:20Z

Well couldn’t you try out the last few versions and check whether it works? Knowing which version doesn’t have the problem would be a great benefit in solving it.

Ilolka1337 · 2020-07-23T10:45:18Z

@weisJ in 2.4.2-SNAPSHOT JPopupMenu works again and without JPopupMenu the white background pops up again

Ilolka1337 · 2020-08-08T10:40:48Z

@weisJ my program just crashes after I go to one of the tabs where JList is used

Ilolka1337 · 2020-08-08T10:41:23Z

@weisJ
Version: 2.4.3 SNAPSHOT

weisJ · 2020-08-08T12:51:29Z

Please create a separate issue with the necessary information.

Ilolka1337 · 2020-08-10T13:03:56Z

@weisJ
I began to notice that the problem is not only in ComboBoxes, when I am in the program menu for a long time, the same thing happens, I minimize and re-deploy the program and a large number of copies disappear. How can I help you reproduce this problem?

weisJ · 2020-08-10T13:19:12Z

You can do the following thing:

Try out different monitors (if possible).
Try out different screen resolutions.
Try out different scaling factors.
Try out different versions of Java (Preferably fresh installations)
- Also try with -Dsun.java2d.dpiaware=false and -Dsun.java2d.dpiaware=false.

To get a grasp on this issue its necessary to know what parameters cause it.

Ilolka1337 · 2020-08-10T14:24:03Z

@weisJ
his problem is not displayed only in the usual laf
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
I also noticed in DarkLaf a very small Font, could you fix it a little later?

Ilolka1337 · 2020-08-10T15:02:51Z

@weisJ

Try out different versions of Java (Preferably fresh installations)
Also try with -Dsun.java2d.dpiaware=false and -Dsun.java2d.dpiaware=true.

does not solve the problem

Ilolka1337 · 2020-08-10T15:07:23Z

@weisJ
everything that you wrote above has been checked many times and it works as a solution to the problem, but I would not want to switch the screen resolution just because of one program

weisJ · 2020-08-10T15:39:26Z

I am not asking you to permanently change your screen resolution but to find out the threshold where the issue starts to appear and tell that to me.

weisJ · 2020-08-10T15:39:48Z

@weisJ

Try out different versions of Java (Preferably fresh installations)
Also try with -Dsun.java2d.dpiaware=false and -Dsun.java2d.dpiaware=true.

does not solve the problem

Which versions of java did you test it on?

Ilolka1337 · 2020-08-10T15:46:26Z

@weisJ

Which versions of java did you test it on?

Java tested versions:
java 8 build 202
java 8 build 201

weisJ · 2020-08-10T15:47:42Z

From the readme

The LaF is compatible with Java >=1.8 (you need >=1.9 to get proper scaling).

Please try a java version >= Java 9

Ilolka1337 · 2020-08-10T15:49:51Z

@weisJ

Please try a java version >= Java 9

but then I will have problems with other applications, they will appear hazy as if they were washed out with soap

Ilolka1337 · 2020-08-10T15:51:47Z

@weisJ
if i test it there can you fix it for Java 8?

weisJ · 2020-08-10T15:53:27Z

This is absolutely not relevant to the issue. Again I am not asking you to stick with this setup but to tell be what setup works for you.

if i test it there can you fix it for Java 8?

I do not intent to support High dpi scaling on Java versions older than 9. What you are experiencing is probably a misconfigured java installation, where the DPI scaling mechanism for javaw.exe or java.exe isn't configured properly.

Ilolka1337 · 2020-08-10T16:05:36Z

@weisJ

I could see the correct operation of the program in Java 8 only when changing the screen parameters from 4k to 1920x1080

Ilolka1337 · 2020-08-10T16:06:38Z

@weisJ
on Java 9 everything is stable could you solve this problem on Java 8?

weisJ · 2020-08-10T16:09:53Z

Just to clarify the situation:

Find java.exe / javaw.exe (for Java 8)
Right click -> Properties
Go to Compatibility tab

How does this tab look for you?

on Java 9 everything is stable could you solve this problem on Java 8?

Well as I have said before I won't do any compatibility changes regarding high dpi issues for Java 8. The best I can do is disable the custom decorations if Java 8 is used.

weisJ · 2020-08-11T19:08:20Z

I also noticed in DarkLaf a very small Font, could you fix it a little later?

This is also caused by incorrect scaling and should be fixed by using Java 9. Though you can manually increase the font size with the following code:

ThemeSettings.getInstance().setFontSizeRule(FonSizeRule.fromPreset(FontSizePreset.Large)); // Or some other preset.

Ilolka1337 · 2020-08-12T00:18:23Z

@weisJ
why don't you want to do at least screen resolution support for Java 8?

weisJ · 2020-08-12T10:08:27Z

I will still try to fix the issue for you but I can’t promise that this is something thats in may hand. The fact that it only happens with Java 8 indicates it may be a JDK specific bug.

You will still have to tell me the scaling/resolution thresholds where the issue appears. Also please answer my question regarding the compatibility settings if your Java installation (both 8 and 9).

Ilolka1337 · 2020-08-12T13:44:48Z

@weisJ
I can't seem to edit the high resolution settings for a specific program, as for some reason I don't have permission to do this, although I have administrator rights

weisJ · 2020-08-12T16:17:03Z

Did you follow these steps?

Just to clarify the situation:

Find java.exe / javaw.exe (for Java 8)

Right click -> Properties

@GraxCode
This looks like a slightly different problem to me. Rather than what is happening here, there seems to be a problem with the painting of the tooltip shadow. This may be caused by some weird alpha compatibility. What desktop environment are you using and does this issue occur every time?

GraxCode · 2021-03-14T10:36:06Z

I am on KDE-Plasma 5.20 (Framework 5.77). This always happens the first time hovering on something after starting the GUI. After the first hover, it doesn't occur anymore.
