Bug ID: 205049 Summary: garbled graphics Product: Drivers Version: 2.5 Kernel Version: 5.2.15-200 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: lechp@onet.pl Regression: No
I'm getting severe graphics glitches in the desktop environment (XFCE, Fedora 30, on Lenovo Ideapad 330-15ARR with Ryzen 3), including text, text cursor, images, buttons and other GUI elements including screen brightness pop-ups. The annoyance level is severe, and usability is also affected. As can be seen in the attachment, the output of "uname -a" is partly garbled. In this case I know roughly what the output should have been, but I would be wary of doing extensive debugging if I can't trust what I see on the screen.
Some of the errors last for about a second before self-correcting. Others persist until some activity like clicking on a button with the mouse 'prompts' the affected area of the display to be refreshed.
How to reproduce: Normal interaction with D.E. using mouse and keyboard.
Temporary workaround: Select kernel version 5.1.20x or older when restarting.
