I was getting some graphic glitches when ever I was using a 125% scale for my desktop.

For instance, some windows where not been drawn when maximizing.

I'm using Plasma, and this option is present in the monitor resolution settings.

I'm not sure if issue is also present in MATE.

At first I tried all options I found about tearing preventing in KDE's settings. As well as some option called "Tearing Prevention" for the Intel driver I found on some pages.

What really bug me was an issue with VLC when using a dual monitor configuration, were VLC was unusable because it was glitching out very badly. Same thing was happening with KRDC.

The vlc issue can be seen in this forum post: https://www.reddit.com/r/kde/comments/kdic9b/vlc_glitching_out_on_my_second_monitor_resizing/

Apparently, in that post is mention that x11 could be the culprit, and that "wayland" could be used instead? I know so little about x11 that I'm not sure I want to change from that to use something I know even less about xD

Any way, I want to share a little work around I found by deleting "ScreenScaleFactors" in ~/.local/kdeglobals

This "workaround" does brake some scaling in the desktop though. For instance, I notice some menú icons are not scale up, but in my opinion, it is needed a very sharp eye to see the difference since the scale is very little from 100% to 125% scaling. It IS very noticeable when it comes to the text, and helps me read the screen easier. I guess my eyes are getting old.

Again in the mentioned post, this bug has been reported to x11. Meanwhile I hope my workaround helps someone out there. See you guys.
