Created attachment 124478 [details] Screenshot: The taskbar above Konquerer got lost while taking the screenshot. SUMMARY Sometimes the taskbar vanishes when I start taking a screenshot with the "rectangular area" mode by pressing the print key. STEPS TO REPRODUCE 1. Set rectangular mode by default (not sure if this is necessary). 2. Take a screenshot by pressing print. OBSERVED RESULT If you are (un)lucky in rare cases the taskbar has vanished until the region is chosen and the enter key is pressed to finally take the screenshot, like in the attachment. SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 5.17.4 KDE Frameworks Version: 5.65.0 Qt Version: 5.13.2 ADDITIONAL INFORMATION Scaling: 1.5
Weird, I've never seen this.
Created attachment 124498 [details] Screenshot, with with even more glitches. (In reply to Nate Graham from comment #1) > Weird, I've never seen this. Indeed, and it happened again! However this time also the menu of the KDE Helpcenter I opened shows a glitch: Where the titlebar of the KDE Helpcenter should be, there's now the one from Okular, which I have opened. Secondly, the menu item text are cut horizontally. There seems to be something very weird going on with the rendering under special circumstances as it does not happen always. For debugging purposes, here's also my graphics setup: Graphics: Device-1: Intel HD Graphics 620 driver: i915 v: kernel Display: x11 server: X.Org 1.20.6 driver: intel unloaded: modesetting resolution: 2560x1440~60Hz OpenGL: renderer: Mesa DRI Intel HD Graphics 620 (Kaby Lake GT2) v: 4.6 Mesa 19.3.0
Addition to the above post: Okular was on the same virtual desktop as the KDE Helpcenter. However, other apps like Systemsettings and Dolphin were also opened on the same virtual desktop.
Could it be related to 385885?

Created attachment 124678 [details] Screenshot with severe glitches. The bug does not seem directly related to the task bar but rather to the rendering of the windows or grabbing the content from the graphics buffer. The windows in the screenshot I took yesterday are completely torn apart.
I believe this had to do with the xf86-video-intel driver I had used before. This driver also caused massive flickering on screen recordings and resulted in paintings of background window parts in the foreground in the recordings. Removing it and using the modesetting driver resolved these issues.
