[Bug 1651520] Re: Scrambled UI: Text in the Unity windows disappears/mixed after the resume from the screen idle state
Christopher, *-rc versions are the release Candidates, once I installed it (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9-rc5) to check the same bug (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1641152) in November and ended up without WiFi. I can't work on *-rc. The bug reproduced after the idle state, laptop lid closing or waking up from the sleeping mode with frequency about once per ~20-30 such actions. The probability seems to be higher when there are more opened windows and external monitor is plugging. In fact, the last 2 issues appeared on plugging the external monitor after the sleep mode. However the bug sometimes (about twice during 4 months) reproduced even on pure laptop without any external devices. I think that you don't have many reports about this bug only because the reporting should be done manually. Moreover, it's extremely hard for an ordinary user to perform such reporting when the UI is totally broken and apport-collect doesn't always success to report even if it was called (as nico mentioned, and I also had the same issue with the apport-collect). --- Info about the kernels: [a few older kernels (< 4.4.0-50) have the UI scrambling issue] -4.4.0-51 - OK: UI scrambling has never occurred, but sometimes (when UI scrambling occurs on another kernels) on this kernel system windows become non-sensitive to the mouse clicks: shortcuts on the desktop are clicked behind the foreground window instead of it. This can be fixed by closing and reopening the window (which does not help on another kernels with the UI scrambling issue). On this kernel the windows can always be moved using the title panel (the top bar of the window) even when the remained part of the [foreground] window is not sensitive (transparent for the mouse clicks). -4.4.0-53, 4.4.0-57, 4.4.0-59 - UI scrambling issue - 4.9.3-040903 - under the evaluation. It survived the stress testing without any issues: intentional subsequent lid closing, laptop suspending and external monitor plugging (up to 20 times).
