This has nothing to do w/ SDDM, you're suspending from a lxqt/x11 session.
Please adjust the subject, restarting sddm only "helps" because it kills the X11 server and the session and everything.

The problem is likely some compositor (picom? try to kill that intead) and the cause likely

some VRAM decay and this service not properly working.
Try to use a permanent storage (disk, not ram) to preserve the VRAM.

On top of that you're mounting ntfs, so standard disclaimer: 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

It's picom

Already did that ever since I installed Arch Linux

reboot windows and linux twice for voodo reasons.

I don't use hibernation ever, so it's kinda unnecessary

So does killing/restarting picom help?
(You could also just establish a sleep hook intead of dealing w/ the VRAM preservation)

Will do, does that mean VRAM preservation is bad?

It means it likely doesn't work (as expected)
The default storage location is in your RAM, if you're short on (free) RAM but have plenty of VRAM, you're gonna run into the limitations of that approach.

If you don't run into further roadblocks and please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
