CLS on true color screen

[blackborn66]

I tried a AQB program in true color (WinUAE with uaegfx):

The CLS in a window did nothing.

If I do open a old school SCREEN first it works.
With hicolor screenmode or 8bit (uaegfx) it works too.
Only true color seems not to work
And it was all on WB 3.9

It's also in WB 3.1

But! Not always in true color (32bit BGRA).
Only in modes higher than 800x600 - starting with 1024x768

And! It's also in hicolor (16bit PC)
But! The problem comes only in modes higher than 1920x1440 - starting with 2048x1152
And it doesn't matter if I turn down the used colors number in ScreenMode

you can use this little test:

OPTION EXPLICIT

FOR i AS Integer = 1 TO 10
    cls    
    locate i, 5
    PRINT "round "; i
    sleep FOR 0.8 
NEXT i

AQB's CLS implementation is very straightforward:

Move (_g_cur_rp, 0, 0);
ClearScreen(_g_cur_rp);

maybe this is a bug in the RTG implementation you're using?
