<pre>When using the first patch (<a href="show_bug.cgi?id=94250#c4">comment 4</a>), the code did not exit at the new
assertion, but at the one from before (from <a href="show_bug.cgi?id=94250#c3">comment 3</a>).
I think I saw it one time exiting with (but failed to save the log and core
dump):
(EE) sna_dri2_schedule_flip:3078 assertion 'info->front == front' failed
And the new patch (<a href="show_bug.cgi?id=94250#c5">comment 5</a>) unfortunately did not fix the problem. After a
couple of tries the code seems to exit at one of two assertions. I will add the
Xorg logs and corresponding stack traces. One of the assertions is
"'info->front == front' failed" from above, so I got the log and stack trace
for this one.</pre>
