Plasma tearing on amd, sddm too small

Support KDE Plasma

Yo!, I’ve been having issues with Manjaro KDE on the unstable branch.

My issues are mostly in the startup, with the most glaring one being KSplash not being the correct resolution, leaving a ugly green bar on the bottom of the screen, the wallpaper not configuring correctly and Plasma not upscaling correctly, due to the monitor not being 1920x1080 by default, and having artifacts on Yakuake and Konsole.

Here’s my inxi -F info.

Hello,

For the tearing part, do this:

Not sure i follow this part. Can you elaborate?

My screen looks weird with a big green ribbon at the bottom of the screen when i start X and KSplash starts, i think it’s just the monitor, because it’s an old LG TV .
