Hi
I got a Raspberry Pi 4 board with 8 GB RAM today, and tried both KDE Plasma and Fedora Workstation images on it. While the workstation (with Gnome) works pretty well, the Plasma desktop is quite sluggish when it comes to graphics. Moving windows around a bit fast, tool-tip popups on taskbar elements etc. are noticeably sluggish and have significant response delays. Gnome desktop does not have any such issues.
Both are running the same kernel versions. But they are two different images (both downloaded from Fedora website), so I don't know if there are any relevant differences in the pre-installed packages.
Any ideas on how to rectify this? I was on KDE/X11 most of the time, and during a brief testing with KDE/Wayland, it didn't fare any better.
Thanks,
Syam

Plasma 5.27 has just been released to the stable repo. Have you tried that?

Yes. I had done an update yesterday and it is indeed 5.27.
I disabled blur desktop effect and that has resulted in some improvement in graphics performance.

As this is a Raspberry Pi, I assume it doesn't have a GPU, so anything with a graphics load will probably be slow, including the desktop itself. You might be better with a more lightweight DE.

GNOME has some heuristics to disable fancy graphical effects in some cases (e.g. running in a VM). That may be kicking in on this system, and accounting for at least some of the difference if KDE doesn't do that?
I found this for a virtual machine, maybe it can help.
