What were you trying to do?

Hi,

When I want to export my project Natron crash everytime.

I tried Flatpak Version and and portable version from Natron's website. And have the same problem.

Here is the return from terminal.

I have another PC which is running under Xbuntu and the export is working fine, but it is old and I prefer use my recent PC.

Thanks for your help

Are you running Wayland? What graphics card and driver are you using?

Looks like an issue with Qt4 and OpenGL.

---

I run Natron on Ubuntu 22.04 myself and it works fine here, both the 2.5.0 release binary and RB-2.5 from source. I use X11 and Intel gfx.

Hi rodlie, thanks for your reply.

I made another test this morning, I start my ubuntu's sessions from X.org and it seem to work.

I will make another test with other graphical server.

The result of :

lspci -vnn | grep -A 12 '\[030[02]\]' | grep -Ei "vga|3d|display|kernel"

is

0000:00:02.0 VGA compatible controller [0300]: Intel Corporation AlderLake-S GT1 [8086:4680] (rev 0c) (prog-if 00 [VGA controller])
	Kernel driver in use: i915
	Kernel modules: i915

Edit : After working on my project all this morning, I have the same problem :

X Error of failed request:  BadAccess (attempt to access private resource denied)

  Minor opcode of failed request:  5 (X_GLXMakeCurrent)

Wayland or X11 is the same issue.

I precise if it's important, the export seems to work correctly (range from 0 to 1500), but my entire project is 58560 frames.

Thx for your help
