Hi,  
some other people have reported here in the form I am also experiencing problems after waking my machine from sleep. I was able to capture a screenshot while the bugs occur.

 ![Screenshot](https://forum.endeavouros.com/uploads/default/original/3X/c/a/cad913fca1e8d81e7bf51704924e71e91fe3d425.png)

The error only occurs under Wayland not under X-Window.

So far I have applied the tips of the following forum posts:  
[Plasma Wayland graphical glitches after waking from sleep](https://forum.endeavouros.com/t/plasma-wayland-graphical-glitches-after-waking-from-sleep/45434) Increased my SWAP to 32 GB as suggested → did not fix the issue  
[Graphical bugs with nvidia gpu](https://forum.endeavouros.com/t/graphical-bugs-with-nvidia-gpu/25730/1) → only applies to GNOME and was already fixed as of driver version 515.43.04  
[Severe Rendering Issues on Latest Nvidia Driver](https://bugs.kde.org/show_bug.cgi?id=424311) → was a regression in the 450 nvidia driver fixed in 455 I am running 535

I would appreciate any help or reports that confirm the behaviour.

# nVidia resume from suspend

```auto
sudo nano /etc/modprobe.d/nvidia-power-management.conf

```

Then add the following line

```auto
options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp

```

See point 10 here:

> **[NVIDIA/Tips and tricks - ArchWiki](https://wiki.archlinux.org/title/NVIDIA/Tips_and_tricks)**

And have you enabled the nVidia services?

The above worked for me on a Legion 5.

This works 🙂 thank you so much.

In the mean time I found that `plasmashell --replace` in krunner also fixes the issue until the next suspend. I also was able to find a KDE Bug [[NVIDIA] Graphical glitches and unresponsive after waking from sleep](https://bugs.kde.org/show_bug.cgi?id=448866) that describes the observed behavior. Though no solution was provided there yet. I will forward your solution to that Bug report so that other people facing the same issue may resolve it this way.

Again thank you so much for the solution.
