Description Michael Groh 2010-11-04 12:14:25 UTC
Hello everyone.

I am playing Heroes of Newerth from time to time. I am using libgl1-mesa-dri-7.10.0+git20101103.ab2305b5-0ubuntu0sarvatt2~maverick from the xorg-edgers overlay on kubuntu 10.10. 

Everytime i am playing HoN, there is this blue noise. It started appearing 1-2 months ago. Even when you have no account, the bug is visible on the login page using the linux client here: http://www.heroesofnewerth.com/download.php and if someone needs to get ingame, i can provide them with a testkey :)

i am happy to help, and if any information is missing, just ask.

Not sure since you don't have any of the hardawre information in here (http://intellinuxgraphics.org/how_to_report_bug.html), but I'm guessing you're on a G965 or GM965 chipset?

    drm/i915: fix regression due to ba3d8d749b01548b9
    We don't track gpu flush request in any special way. So even with
    obj->write_domain == 0, a gpu flush might be outstanding but no
    yet executed. Even worse, the latest request might use the object
    only for reading. So and unconditional call to object_wait_rendering
    is needed for !pipelined.
    Hence revert that patch fully and untangle the flushing from the
    synchronization again.
