Mouse pointer sometime large

Desktop Environments Plasma
1

Hello,
I have a strange behavior in KDE. In some applications the mouse pointer is displayed large. On the desktop, browser, terminal or Thunderbird I see my normal mouse pointer in normal size. As soon as I move the mouse pointer over pamac or Delfin (Jellyfin Client), the mouse pointer is clearly displayed larger. Does anyone have an idea?

I have the effect on my notebook screen (wayland, scaling 150%) as well as on my external monitor (wayland, scaling 100%)

I use an asus rog zephylus g14 GA403UI (AMD, RTX). 6.12.16-1-lts, Plasma 6.3.1

thanks

Hey welcome @mr.psyc :slight_smile:

I totally have the same behaviour happening from time to time, on a machine running KDE, wayland.

I remember looking into it, finding a sort of explanation, but I totally forgot what it was all about :sweat_smile:
I’ll have a look on this very machine to see if I saved the whys and hows somewhere…

cheers

Could it have anything to do with this feature (not sure).https://discuss.kde.org/t/shaking-my-mouse-renders-it-massive/17473

It is a KDE Accessibility feature that is enabled by default. You can easily disable it.

If you’re talking about the cursor only appearing large on specific apps, it seems some GTK apps don’t recognize the smaller, default size. I have that issue with Gear Lever…

This is a interesting to read about the problem:

GTK has had difficulties for a while getting its pointer sizes right with fractional scaling on Wayland, but this should all be solved in GTK 4.18. No more huge pointers. Fixing this also required changes on the mutter side.

This is a bug in gtk that should be fixed in the next release in march. I have been dealing with it for the last 6 months. Thats how often Gnome makes new releases. In the meantime, I have patched the gtk4 package on my system. Using the patch from here

They have already solved the issue so no need to bug them, but like I mentioned earlier. This won’t be fixed until the next release.

Hello Keescase,

Thank you for this link. I think it describes exactly the problem. Unfortunately, I didn’t quite understand what I should or can do, but it has also been written here that a solution could come in the next update.

best regards

The only thing you can do I think is choose a mouse pointer that doesn’t show this behaviour.
For example I have a mouse pointer called Layan (it is in the Aur) that I use in Plasma as well as in Xfce without any problems.

Unfortunately, this mouse pointer does not work for me. I have the same effect. But thanks anyway, I have once again learned a lot and understand the context a little better.
I hope that this small optical error will be solved in the next update.

thanks you very much to all

Installed Delfin and the pointer doesn’t show any strange behaviour.
So I wonder if this has anything to do with that you have a LTS kernel installed, and I have the latest kernel available installed (6.13.4). If that’s the case this problem will only be solved when the LTS kernel gets updated I guess.

Hello,

because of this hint I have tested the current kernel. 6.13.4-arch1-1
But I also have this effect here (I test with pamac GUI).

Too bad, but many thanks for your tips.

Hello,

my error description was not quite correct. I am only now using 100% scaling on the external monitor and so I don’t have the large mouse pointer.

I use a scaling 150% on the high-resolution 14 inch notebook screen and thus have the large pointer reproducibly in a few apps. It’s just a small visual glitch :wink:

thank you very much for the links, they are very informative.

Should I mark the thread somehow?

your forum is cool, cu soon.
