I experienced a bug on radeon games on my last openGL project,
It appears that in fullscreen mode (only) the games doesnt display correctly , you show lines moving fast on the whole screen , but after the splash screen ( which dispays correctly and is in openGL too)
It seems that the problem is related to VSync because when I set wait for VSync in the openGL dispay settings , the game dispays better ( no more lines but a little flickering …)
If I take a screeshot of my screen , It actually displays correctly in Paint , so the problem is directly related to display and dispay only (no openGL error code, no others bugs in the game …)
I ve tried to comment some pieces of code to show which part of code causes the problem but I can find it .
So have you ever experienced problem like this and how to fix it
Thanx in advance
