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. Tell me if you need some more info.
