<div>
<pre>After xf86-video-intel 2.21.5 upgrade, when I try to run any 3D apps (windowed
or fullscreen) with wait for vblank turned of I get only blank content of the
window/app. Testcase:
vblank_mode=0 glxgears
window content is black
without vblank_mode=0, glxgears run just fine
After downgrading to 2.21.4 I can't reproduce the bug anymore.
Tried several times upgrading/downgrading and testcase was 100% reliable.
Intel HD2000 (i5-2400)
xf86-video-intel 2.21.5
mesa 9.1.1
xorg-server 1.14.0
There are no error messages in Xorg.0.log, dmesg, no errors in i915_error_state
Thanks !</pre>
