Priority: medium Bug ID: 80235 Assignee: dri-devel@lists.freedesktop.org Summary: Artifacts in kernel 3.16-rc1 and HD 7750 Severity: major Classification: Unclassified OS: Linux (All) Reporter: rgfernandes@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
Created attachment 101360 --> https://bugs.freedesktop.org/attachment.cgi?id=101360&action=edit Image showing the artifact
I have updated the kernel to 3.16-rc1 and got some screen artifacts. I have bisected the problem and found that the commit 1aab5514ca9604e0263f658a067da0189c86a35b (drm/radeon: rework page flip handling v3) is causing these artifacts. I am attaching some images to show these artifacts. There is also a artifact in steam logo inside Portal 2 (the background texture seems to disapear) that does not happen in commit just before (1a0e79184132c5dc0e03a4047eacecc52c24deae). I got 2 freezes too. The computer does not respond anymore, I can't switch to console and after some seconds the computer reboots. But I not sure if this problem is in this commit (1aab5514ca9604e0263f658a067da0189c86a35b).
