I have been running Manjaro KDE Plasma on my desktop for a few weeks. Previously, I ran the Cinnamon edition but switched to see if the official versions were more stable. However, I have a couple of reoccurring video glitches. Also, I dual boot with Windows, using different hard drives. I have not had any similar problems using Windows, so I believe the issue is strictly with the Manjaro installation.
Often when I shutdown my system, a flash of pink, glitched lines briefly appears across my display. The system still shuts down though. Also, it tends to occur when I shutdown after waking the system up from sleep mode (not immediately after though, I can use the system for hours before shutting down). It happened more frequently when I ran the Cinnamon edition, sometimes when I was using light applications, such as Libreoffice and Okular. But the main way to reproduce the glitch is to put the system to sleep, wake it, then shutdown.
The other issue, which I believe to be related, is that sometimes, after selecting Manjaro at the GRUB boot menu, the login screen will not show up. A black screen is all that appears. Resetting seems to be the fix, but I felt like it might be related.
So far, I have tried switching kernels, from the latest 5.8, to the LTS, 5.4. Also, I have tried updating the graphics drivers, using both the Manjaro Settings Manager and the Manjaro Hardware Detection command. Both state that I have to correct drivers installed. Though I still believe the issue is with the drivers. One theory I have, based on reading various posts online, is that I will simply need to wait for more updates, to make the system more stable.
Any help would be appreciated. This is my first post, so kindly let me know if I can improve my forum etiquette.
