Setting as Confirmed since Nate could reproduce it in https://bugs.kde.org/show_bug.cgi?id=474382
Comment 2 Nate Graham 2023-09-12 14:29:13 UTC
Yep, can reproduce. Firefox is in Native Wayland mode. The problem is also seen in other native Wayland non-Libadwaita apps GTK apps, such as Gedit.

In Native Wayland Libadwaita apps, I see something different: the cursor it still not the right size, but it's a *different* wrong size, and the cursor theme is also wrong.

I am experiencing this with qtcreator XWayland, cursor theme is off as well.

I don't reproduce it in Firefox (ubuntu snap) in Wayland native.

So, my previous bug was closed and marked duplicate of this - which seems correctly. Just wanted to bring up the other half of my report which is the video can 'jump' a bit when moving the mouse (and it becomes the right size again). I have noticed the same frame jumping/slight ghosting also in two Proton steam games (Rome 2 Total War & Attila Total War) where the cursor is fine, but I get the jumping/frame ghosting. Switching them from full screen to windowed and the ghosting stops. 

At this point not sure if they are related - or if I should create a separate bug for this side of my original report.

Just an update on the games and flickering: running in gamescope and they are fine, so, i do think it is a kwin issue.

The cursor in the screenshot is not only tiny, it looks like Adwaita to me. Probably your Firefox is picking cursor settings from the desktop portal (widget.use-xdg-desktop-portal.settings=1 in about:config, or GTK_USE_PORTAL=1), and you don't have xdg-portal-desktop-gtk installed?

That said, GTK3 just merged this:
https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/5481
which might improve the situation with similar problems, by using the 2x cursor from Breeze when 3x is absent, instead of falling back straight to 1x. I guess then GTK3 apps under wayland would behave like Electron apps, i.e. at 2.5x zoom, they will use a 2x cursor which is smaller than in KDE apps but still usable.
