Distored image on wake

After my previous screen issues, I’m taking any new and old issues more seriously.
Whenever I wake my laptop from sleep, it greets me with a distorted image (attached) for a few seconds before my lock screen is shown.

I use the KDE edition.

No idea if its related or not but you have BIOS updates.

I doubt it’s related, but how do I update it? Do you know if they are side-effects?

Depends on your model/maunfacturer … consult your documentation.
Some UEFI environments allow updating from within (by pointing at the update file), others require a windoze environment and in the case it is not dual-boot you can use something like hirens bootcd.

Alright. I might just forget the update
