Date: Mon, 30 Aug 2010 13:45:38 -0700 (PDT) [thread overview]
Message-ID: <bug-29894-502@http.bugs.freedesktop.org/> (raw)
https://bugs.freedesktop.org/show_bug.cgi?id=29894
Summary: KMS regression in 2.6.35: Flicker and half-rendered
scenes in SDL games with Radeon RV770
Product: DRI
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: marti@juffo.org
I am getting severe flickering in multiple SDL-based games with Radeon HD 4870
(RV770)
Games tested that have this problem:
* World of Goo (SDL, 32-bit)
* Frets on Fire (Python, SDL, true 3D, 64-bit)
* Aquaria (SDL, 32-bit)
----
* kernels 2.6.33.4 and 2.6.34.2 are good even with KMS enabled
* kernels 2.6.35.4 with KMS disabled is good
* kernels 2.6.35 and 2.6.35.4 with KMS enabled is bad
The problem manifests itself in substantial flickering; most frames seem to
render OK, but a couple of times every second there's an incomplete frame. The
incomplete frame looks like a half-rendered scene, with some objects missing.
Using xorg-server 1.9.0, mesa 7.8.2, xf86-video-ati-6.13.1
(also tried mesa from git)
Normally I have 2 screens attached, but this time I also tried disabling the
second screen and unplugged it entirely.
