Comment # 15
on bug 98784
from Michel Dänzer
Thanks for raising the issue with Croteam. (In reply to Germano Massullo from comment #14) > I've just double checked and we definately set GL_DRAW_FRAMEBUFFER to 0 > (default back buffer) before clear. When I look at the trace from comment #10 in qapitrace, I see a bunch of glBindFramebuffer(GL_DRAW_FRAMEBUFFER, ...) calls in frame 0, the last one being glBindFramebuffer(GL_DRAW_FRAMEBUFFER, 31) After that, there are no glBindFramebuffer calls for a long time. GL_DRAW_FRAMEBUFFER isn't set to 0 before frame 777, after which the flickering stops, and the window contents start looking as expected. I've now also confirmed this with running glretrace in gdb and setting a breakpoint at _mesa_BindFramebuffer. I'd definitely like somebody else to confirm the above though, to make sure I'm not missing anything.
