Bug ID: 108221 Summary: amdgpu: mouse cursor flickers + black boxes Product: Drivers Version: 2.5 Kernel Version: 4.3.0-7 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: frederic.santos@u-bordeaux.fr Regression: No
For kernel >= 4.3.0-3: Mouse cursor constantly flickers and disappears. A black box stays on screen when clicking on some elements of the GNOME desktop. More generally, there are problems with screen refresh. The problem is present only since an update to the kernel 4.3.0-3, the first versions of 4.3.x were OK for me. Recent updates of the kernel and amdgpu did not help.
