After exiting games such as Prison Architect and Albion Online the entire interface goes blurry especially the fonts. Running a game again restores the usual look of the interface, as does relogging/rebooting. When you hover the mouse over a particular application the fonts go slightly sharper (although not as usual) and return to their even more blurry state when moving the mouse from them. This issue has been reproduced on both Kubuntu and Archlinux using out of the box settings. The system in question contains an NVidia 1070 using the NVidia proprietary drivers. On Archlinux I have tried the 396.24 driver, on Kubuntu I have tried 340.107, 387.34, 396.24.02 drivers. Additionally, the system has three monitors although the problem occurs even if two are unplugged and the problem occurs across all monitors. What I have tried: - I have 3 monitors (all 1080x1920) on an NVIDIA GTX 1070 on the 396.24.02 driver. I have tried earlier versions of the driver but the problem still exists on those too. Problem occurs on all monitors. - Tried resetting my /etc/X11/xorg.conf using the NVIDIA tools - Tried ForceCompositionPipeline and Force FullCompositionPipeline in my NVIDIA settings - Tried different themes - Tried screwing around with hinting style and settings - Tried manually setting my DPI settings - Tried configuring the resolutions of my screens to their actual values instead of auto - Tried setting GL_YIELD=USLEEP (suggestion from #archlinux on Freenode) Note that I originally posted this on https://www.kubuntuforums.net/showthread.php/73871-Blurry-text-when-exiting-from-game-and-UI-problems but nobody was able to help me. The issues mentioned there about the clock/settings don't seem to be happening on 5.13.2 however.
Can you post output of xrandr -q before and after the issue.

One more thing can you post a screenshot of the blurry text
Created attachment 113644 [details] Screenshot of issue
Looks like I spoke too soon as the time freezing in the panel has returned. Turning on Autohide makes the panel redraw I believe, which results in the time being displayed again properly.
Do you have nvidia? If so do you have something non-default in the nvidia-settings "antialiasing" tab?
If you can provide the information requested in comment #6, please add it.
I remember we had a similar report. Clearing the NVIDIA configuration solved it, but I cannot find the ticket right now.
See bug 406667.
