Intel UHD 630 having stuck/repeating frames issues

[DestroyFX]

Hi there, I wonder if I can get a solution from my problem.

I do have thin computer (Lenovo M70q) with an Intel 10500T and a iGPU (Intel UHD 630).
I'm using the Modesetting driver. I did try the Intel DDX drivers but got some other different issues.
I have 3 monitors connected to the system (1xDP, 1xHDMT, 1xVGA).
Using Plasma DM.

The main issue [With Xorg], I would say, is that very regularly, the graphics in a specific window stop updating and get stuck like a broken CED (Think video vinyl disk getting stuck on a track, few last frames repeated in loop), can be any program including konsole but it usually append the most with my youtube browser and the console when i'm doing stuff that produce a lot of scrolling. I usually have to close the affected program and re-launch it to get rid of the issue, with is quite annoying. Games and video playback with mpv, using vaapi, for some reason, don't seam to be affected and run fine. Moving the affected window kind of "unstuck it" while the window is moving but get right back into "stuck / repeating few last frame" mode after I stop moving the window. I did not see anything in X log.

I did try to find solution and found some partial thing, like use hardware video decode for youtube.. but it's does not fix the issue, it make it just append less often .

Ugly workaround I got so far :
* Using Wayland, what I do now (get rid of the stuck/repeating frames issue, mostly but bring a ton of other very annoying issues. The issue still append from time to time but just clicking in the bugged window fix it.
* Using Windows 10 (Fix everything BUT games have a very tendency to crash the system, I would rather not use Windows but so far is seam to be the only stable fix as I can just game on my real desktop computer instead).

Fixing the issues I get on wayland could be a solution, if it's even possible. Here are the issue I get on Wayland (right now):
* When the system put display in sleep, it forget where the windows where, so when I wake them up, I then have to reposition all the windows (most annoying issue). Got to increase the sleep time to 2HR instead of 15min so I don't have to do that more than two time a day
* If the computer put the displays to sleep **after** I did unplug and replug the displays/usb device (like when I unplug all so I can plug them on my gaming PC), like a few hours after, the displays sometime, will not wake up from sleep and when that append, the keyboard numlock led is stuck on. The system look like it's crashed but the kernel is still alive (can ssh to it, and it clearly see detected USB devices in log if I try to replug the keyboard).
* There is no proper hardware video acceleration support for vaapi (probably lacking proper app support). I mean, Firefox can play 4K videos using vaapi, no problem, but mpv and vlc not only use vaapi but there is some kind of loop that get GPU utilization to 100% and drop fps to 5
* Games can't change screen resolution. My main screen is 4K, the GPU is Intel UHD 630 as mentioned, I can't really game over 1080p resolution on that thing.

Best solution could be to find an AMD version of that system but for now I have that Intel one.

AFAIK in most BIOS you can reserve memory for intel's GPU. Try to raise it (maybe to maximum). Does this help ?
(issue can be because 3 monitors and too less pre-reserved mem)

Thanks for the tip, I did set everything to Maximum.

Now reverted to good old Xorg, will see if I still get the issue.

Have you tried this?

After spending some time on the system, I confirm that none of the suggestions fix the issue.

I have the impression that it append less often but it could be just random doing it's things.

Maybe you can try to use https://wiki.gentoo.org/wiki/Intel#Intel_DDX instead of modesetting ( I am using it also ). Yes, its deprecated but I think it is really faster.

This is my config for this (using an i7-6700) :

Please use also latest kernel (I am on 5.15.79 ) because there have been a few minor versions in the past with strange problems: I had weird flimmering sometimes (but pls dont ask which versions where concerned)
