Fedora 39 KDE spin - Wayland session improvements - thanks and info on current experience

[Amir Khan]

Dear KWin / Plasma Development team,

I have been triaging bugs for KDE for some weeks, but as I have development
experience in C++, C and other languages, I'm keen to get up to speed to be
able to submit bugfixes too, in time. I've been using Fedora 39 KDE spin
for learning Kirigami/QML and plan to move to KDE Frameworks with Qt this
week or next week.

As I'm not in a paid contract currently and don't have any hardware spare,
nor the option to purchase, I'm running Fedora 39 KDE spin in a VM, namely
under Boxes on Ubuntu 22.04, and Virtualbox on Win11. Prior to updating
today, including kwin updates, Plasma under Wayland was unusable. The mouse
pointer wasn't accurately placing, e.g. it seemed a bit off from where the
output of typing was appearing, when running Kate, as the only app running,
or when trying to click on a hyperlink or the address bar when running
Firefox only. *The update I applied today has vastly improved my experience
of Plasma under Wayland, and it is now usable. This is a huge relief
because I understand Fedora 40 won't have an X11 session option at all.
Huge thanks from me for all your hard work!*

I was curious to see how far I needed to push Wayland before it might start
misbehaving. It was pretty far lol!
When I ran four apps, all tiled under Plasma, namely Firefox playing a
YouTube video, Kate, Konsole and Java running Freeplane as a flatpak, I
started to get weird mouse behaviour again: pointer disappearing, pointer
changing based on its expected function, lagging from where it actually was
on the screen. Also, I was getting some flickering on the bottom panel,
though not making the panel unusable. I'm sending this for information's
sake, and will happily submit bugs to Bugzilla under kwin, tagged with
wayland, if I am able to replicate something specific and easily testable.

Meantime, many thanks again, and have a great day :)
Amir.
