Hi,
I have a problem that the mouse cursor disappears after being logged in
for some time (e.g. 15 - 30 minutes,) and while the mouse can still has
en effect (e.g. I can see different elements on the screen getting focus
as I move the mouse, the cursor no longer displays making it practically
unusable.
A reboot is required to get the cursor back.
I see a few other reports of the same problem on the internet, e.g.

The common workaround is to set a software cursor in Xorg.conf. I'm
using wayland and I don't see a way to do that with wayland. I'd switch
back to Xorg with a software cursor if that would work and its the only
workaround.
I didn't have this problem on the previous Debian version, so I'm
considering reverting the kernel to an earlier one to see if that helps.
Does anyone have further tips on troubleshooting this? E.g. should I
diff the changes between driver versions and try to work out what's
changed relating to the cursor? I'm not familiar with display driver
code but I'd kind of be interested to have a look if it was likely to be
of use.
Some system details below.
I've got an older Mac (iMac11,2) and I'm running Debian Trixie on it.
It has RV730 inbuilt video:
$lspci

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] RV730/M96-XT [Mobility Radeon HD 4670]
Subsystem: Apple Inc. Device 00b6
Kernel driver in use: radeon
Kernel modules: radeon, amdgpu
I have this file:
/usr/lib/modules/6.12.63+deb13-amd64/kernel/drivers/gpu/drm/radeon/radeon.ko.xz
which I assume is the driver:
