Sometimes when I resume from suspend, the panel is not updated anymore. E.g. the clock is stuck, hovering items in the task bar does not highlight them etc. When I change anything in the composition settings and hit apply, the panel functions normally again. Not sure if that's related but the "show mouse" effect also has a visual glitch: the pngs used for the rotating rings are no more transparent but have a white background. That, however, is not cured after changing settings. I'm using the proprietary nvidia driver (380.95). Might be related to https://bugs.kde.org/show_bug.cgi?id=385607 ?
I can't find the bug (sorry), but I'm almost positive this is a known issue that was fixed with a newer version of the proprietary NVIDIA driver. Can you update to the latest one and let me know if it reproduces? Thanks!
