raziel_ : A number of fixes have been applied recently for OpenGL Graphics. Please can you confirm if this problem still exists with the latest build from git master?

No need for sorrow. Assigned to LordHoto who has kindly agreed to look at it with his Mac Mini i.e. also BE platform.

I can not reproduce this on my Mac mini PPC, I guess your graphics driver / OpenGL implementation does not support the overlay color format as texture color format.
Since the overlay uses the same format as the OSD (and not the same as the cursor one), it pretty much hints at such a problem. Since other modes use the same color format as the overlay I am not sure whether this is easily fixable, except by converting all the data to RGBA8888 via software.

Overlay and the whole MiniGL implementation is rather limited on my platform
To get an idea of what is working take a look here: http://os4depot.net/index.php?function=showfile&file=driver/graphics/minigl.lha The source of MiniGL

This changes makes the white screen disappear but with wrong UI colors
comment:11 by , 14 years ago
It's getting a little better, speed in 640x480 is nearly back to normal in UI (see below, wrong colors though) Games are pretty much unplayable due to massive slowdown
I uploaded a new .diff file (sorry, no git) which makes the white screen disappear. I can use the menu, start and play games but to the drawback of having a wrong colored UI.
This i use _overlayFormat = Graphics::PixelFormat(2, 4, 4, 4, 4, 12, 8, 4, 0); instead of _overlayFormat = Graphics::PixelFormat(2, 5, 5, 5, 1, 11, 6, 1, 0);
Can someone please explain to me what these numbers describe? So i can test out different settings to find (maybe) one that works for me?
On testing right now i always get a "OpenGLGraphicsManager: Pixel format not supported!"
Thanks a lot

This specific behaviour has been fixed in the meantime.
Sorry, completely forgot about this bug.

Forgot to add
Cursor is drawn (very big as if the resolution is at 324x240 or similar). No OSD when switching between fullscreen/window
