on bug 79850
from Sylvain BERTRAND
Ok. I made a mistake. I inverted the result I debugged for can_flip! It was returning FALSE not TRUE... my mistake and my bad. Now, I got debug version of the ati dri stuff too. Still some weird breakpoint behavior though. But I managed my way with what was still consistent about breakpoint behaviour. can_flip never returns TRUE. All the time FALSE. Yes, awesomenauts does run full screen (1920x1200) No compositing window manager is running (xfwm with compositing disabled). Then we may conclude that awesomenauts is not using root pixmap flip compatible pixmaps. I guess that would be the same issue with "life goes on". It would mean the pixmap transformation is costing too much in time regarding vblank time, making happen the swap in the middle of the visible screen. dirty :(
