Comment # 20
on bug 79850
from Michel Dänzer
(In reply to comment #19) > Only dri2.c:934 make DRI2CanFlip return FALSE. That's while awesomenauts is running fullscreen? So can_flip() also returns FALSE in that case, contrary to comment #7? Apart from backing store, possible reasons I can think of for the window pixmap not being the screen pixmap are: * A compositing manager is running, which doesn't unredirect fullscreen windows. This includes things like xcompmgr -a, which doesn't involve any special effects like shadows or translucency. * The awesomenauts window is redirected automatically, e.g. because it uses a visual which is incompatible with the root window visual.
