Inconsistent cursor size with fractional scaling

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.
