SUMMARY On Firefox (and possible other XWayland applications) the mouse cursor doesn't always change. Examples are when I am over text and the cursor should change to a "text" cursor. Or when I somehow get it to change to that cursor and move away from the text, but it still is a text cursor and doesn't change back to a normal one. STEPS TO REPRODUCE 1. A page where this happens is https://bugs.kde.org/enter_bug.cgi 2. Move the mouse around over the content SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20210128 KDE Plasma Version: 5.20.90 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 Kernel Version: 5.10.9-1-default OS Type: 64-bit Processors: 4 × Intel® Xeon® CPU E3-1225 v3 @ 3.20GHz Memory: 11.6 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics P4600/P4700 This might be unrelated to Wayland or Plasma, haven't thoroughly tested. Maybe this is a Firefox bug in general. Product and component might be wrong.
On Wayland, input is handled by the server (KWin) and the client (Firefox) directly; Plasma isn't involved. Moving to KWin for now. Can you triage this a bit? Does it happens on X11? Or in other apps? Or on other web pages? etc.

Finally, I got around to test a bit further. I cannot reproduce it on Bugzilla with X11, so setting Wayland keyword. Not sure whether it happens on other webpages, I think I mostly noticed it on Bugzilla.
I can also reproduce on other webpages like Wikipedia.
During further investigation, I made some interesting findings. I did not find a Wayland application with this problem (but I also don't know of one that has a text cursor apart from input fields). While testing with LibreOffice, I managed to reproduce the problem (but only when there was no cursor blinking). Also, I noticed that the problem doesn't happen in Firefox if I have systemsettings open focused with a blinking cursor in the text field. I assume that it doesn't have to be systemsettings. In LibreOffice when there was a blinking "cursor", I noticed that the mouse cursor changed from normal to text after moving from normal content over text content in the frequency of the "cursor" blinking in the text field (the same happens the other way around when moving the mouse from text over normal content). There is a delay for changing the mouse cursor that seems to "wait" for the "cursor" in the text field to blink. I thus assume that somehow the text field "cursor" blinking is interfering or limiting some function that checks for the mouse cursor position in order to change it matching the content.
Still cannot reproduce, now with Plasma 5.21 and firefox 86. Can you still reproduce?

I cannot reproduce anymore, so might have gotten fixed somewhere in the meantime.
