https://bugzilla.kernel.org/show_bug.cgi?id=76861 Bug ID: 76861 Summary: radeon: flickering horizontal stripes/lines Product: Drivers Version: 2.5 Kernel Version: 3.15-rc6 Hardware: i386 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: sven.dziadek@xxxxxx CC: bugspam@xxxxxxxxxxxxxxxxx, deathsimple@xxxxxxxxxxx Regression: No Created attachment 137301 --> https://bugzilla.kernel.org/attachment.cgi?id=137301&action=edit Video of my monitor Maybe duplicate of https://bugzilla.kernel.org/show_bug.cgi?id=75921 Recent DRI updates trigger a strange bug with my Radeon graphics card. Horizontal lines flicker. These stripes/ lines start from the right edge of the screen and have different lengths. All colors are visible. The amount of lines depends on the speed of diplay changes. In games/ console scrolling, there is a lot of them. If the pc is idle, I don't see any. Occurs also in tty1 on the text console. I appended a bad-quality video showing this issue. Sorry for the quality, but screencast programs don't record the problem, only the picture as it should be. With 3.15-rc1 it still works fine. In later Kernels, it is black without output. >From somewhere between 3.15-rc3 and 3.15-rc4 (when the black-screen-issue is fixed), theses stripes are visible. They are still there in latest commit: 1ee1ceafb572f1a925809168267a7962a4289de8 Graphics card is onboard: 01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS880 [Radeon HD 4200] (prog-if 00 [VGA controller]) Monitor is attached over DVI. I haven't found any errors in syslog.
