I too have this problem. I am running Gnome (Testing) under Wayland. I have a low cost Nvidia card and use the open source driver. If I use kernel 5.11.1 or 5.11.2 then the cursor is deformed into a skeletal affair (quite ladder-ish), narrow, vertical and about twice the normal height, which changes shape as the cursor changes shape (arrow, hand etc) or when I try a different theme.
If I log into Gnome under Xorg, the problem is immediately resolved. Since Wayland is one of my motivations for using Gnome, this is not my preferred solution! So far I revert to using 5.10.
Sadly a screenshot does not help. The screenshot program substitutes a correct cursor.
This is more than just a Manjaro/Gnome/Wayland problem. It is present on openSUSE Tumbleweed/KDE/PlasmaX11 also. It isn’t window manager specific, same results with KDE, IceWM and TWM. The other thing I have in common with @bobwad is an Nvidia graphics adapter - mine is a Quadro K1100M.
The messed up cursor is present at the login screen before the desktop is loaded and as @bobwad said it’s way more than a cosmetic issue. Changing the cursor theme and/or size makes no difference nor does changing the theme.
Is it maybe an issue with nouveau and kernel support? With libdrm_nouveau2 v.2.4.104-3 the cursor is messed up when booting with kernel 5.11.xx, displays correctly with any previous 5.10.xx or older version.
I would attach images of what an arrow, hand, and text cursor look like but it says I can’t embed media items in the post. I’d make them links but it says I can’t do that either
That is correct, if I try the Nvidia drivers, I’ll have to reinstall the OS completely as I’ll just have a blank screen and I’m not a programmer so the only option I know of is to reinstall and never use the Nvidia drivers again. I’ve tried it several times.
