I assume this only happens with triple buffering as well as page flipping; I fixed a problem like this recently in Mesa git, which commit are you at? I tested: Mesa commit 51a894e6ebc3412a6d634a7378806f137374b09a DRM commit 78034c06dfc0cd79cc47c2daa119ca3ee2a4fed4 Image flickers also with PageFlip enabled and TripleBuffer disabled. I can't seem to reproduce this, but I just pushed some possibly related changes to git. If it still happens with current git, please attach the output of xrandr --verbose; with glxgears, does only the window flicker, or the whole screen? Window flickers also with changes.

It seems to be fixed. Bug appeared again after connecting LCD to VGA output.

(In reply to comment #17) > Bug appeared again after connecting LCD to VGA output. Is the flicker (identical) on both outputs? Are you using sync-to-vblank? I don't have access to external LCD at the moment.
Both images looked same except resolution, when I was testing.
I'm using following drirc file
<driconf>
<device screen="0" driver="i915">
<application name="Default">
<option name="force_s3tc_enable" value="false" />
<option name="fthrottle_mode" value="2" />
<option name="vblank_mode" value="0" />
<option name="allow_large_textures" value="1" />
</application>

I have external LCD connected. Image flickers same on both displays. mesa 6.5.3 xorg-server 1.3.0 xf86-video-intel git 0984c1fc0963f1ebab31f5b8fce5ad4c387fbd2c drm git 638c8087deecdf489eb4f70e82590d1be0c8c942 Created attachment 10155 [details]

Image flickers also with mesa git 90630feeec52c6d4f2a17f75cdf3dab9f5baf923 Okay, I've been able to reproduce this. The problem occurs when Mesa generates damage events for buffer swaps and xf86-video-intel doesn't know to ignore them for synchronising the page contents. It'll be fixed when you build and run xf86-video-intel against xserver master (to become 1.4). |
