KDE Plasma 6 stuttering when switching from X11 to Wayland

I'm using Arch Linux with KDE Plasma 6.3.2 (latest) as the Desktop Environment. I've been using X11 for a long time, but recently due to the issue with NVIDIA's latest driver version, I decided to switch to Wayland.

The initial setup was a success aside from the serious stuttering and framedrops, especially during general usage (without heavy gaming) and watching YouTube on Firefox, even though I'm using a decent laptop. For example, the frame drops in the image below is notorious even when I leave the screen idle without switching to another tab or application. I'm playing a 1080p60 video, which didn't have any frame drops when I was still in X11.

I've tried these things but nothing really helped:

• I disabled the GSP firmware in the NVIDIA driver, because some people told that disabling it can help fixing the issue. When I use nvidia-smi -q | grep GSP, it already outputs GSP Firmware Version: N/A.

• For Firefox-specific issue, I tried enabling gfx.webrenderer.all, gfx.webrenderer.compositor, widget.dmabuf.force-enabled and other things related to hardware acceleration.

• I also found a site saying that I should set KWIN_TRIPLE_BUFFER=0, but I haven't tried it because I don't know what will this variable do.

journalctl -f didn't output anything when the stuttering happens. I'll also be very happy if anyone can tell me other ways to do a proper logging for this specific issue.

The issue only often happen during general usage. It's less likely to happen when I'm playing games, even Wine games don't have that issue.

I also have some other issues when switching to Wayland:

• Vietnamese input (using fcitx) doesn't work on Wine applications. I tried setting fcitx-related variables in ~/.profile but it didn't help.

• When I play games remotely using Steam Remote Play, it throws a bunch of popups require me to allow it, but everytime I reboot these popups appear again. There's no "Allow restoring in future sessions" option. I can temporarily uninstall xdg-desktop-portal-kde to get rid of these popups, but then I can't record the screen using OBS anymore.

• The CopyQ hotkeys that I set doesn't work on Wayland. It helped so much on saving clipboard history, but now I have to open it manually.

At this point I'm really stuck. I've tried searching Google and asking AI applications but nothing helped with my specific issue. If anyone can give me a solution, I'll be very glad since Linux is currently my daily driver. I just don't want to use other OSes.

Re: KDE Plasma 6 stuttering when switching from X11 to Wayland

I'm not sure if I should go back to X11 or try to fix the issue in Wayland.

When I upgrade the NVIDIA driver to the latest version in X11, the games I usually play constantly crashes upon starting, sometimes it can crash the entire computer and I have to force restart.

Of course I've solved that issue by downgrading the NVIDIA driver to 555.58.02, but now that driver and the Linux kernel it requires are much outdated, so I prefer switching to Wayland and use the latest version instead of doing partial update like before.
I don't know if there's also any fix for that specific issue for the latest NVIDIA driver version, but now I'm just don't know what to do.
