Bug Description

When fractional scaling is enabled (I use 250%), the mouse cursor becomes very large when hovering over the desktop and in some applications. It returns to its normal size when moved over the panel, dock and most Gnome apps (evince is a notable exception here). The issue appeared after the update to 23.04.

I'm not sure the problem is really in the extension. I tried the workaround of disabling desktop icons, and indeed the cursor went back to normal on the desktop. However, it's still larger than normal in some apps, including evince.

desktop-icons-ng uses GTK3 so maybe that's the common factor? Basically any older GTK app that has to fake fractional scaling by being over-upscaled and then downscaled in the compositor.

Happen to me here also, 250% fractional scaling. Mouse scaling is off on some applications, such as SublimeText text editor, gnome-terminal (the old one, Console works fine)

Seems the bug only happens when using non integer fractional scaling (such as 2.5x or 250%). When using 2x (200%) mouse still scale ok. And when fractional scaling disabled and setting 200% scaling, also mouse ok.

Found the following errors when setting to 250% fractional scaling :

gnome-shell[4069]: Bug in client with pid 13356: Cursor buffer size (64x64) is not an integer multiple of the buffer_scale (3).

gnome-terminal-[9176]: ../../../gdk/wayland/gdkcursor-wayland.c:242 cursor image size (64x64) not an integermultiple of scale (3)
