Unfortunately, you've missed to include 
- the list of packages that have changed between your last good and your first 
  bad installation, 
- the Xserver log file from before and after you've updated from the user repo.
in your original report.
This way, I was not able to draw the correct conclusions.

I've investigated this myself now:
The problem occurred due to a switch from xf86-video-intel to the modesetting
driver for anything g9+ to address that xf86-video-intel doesn't really have
good support for this hardware: for other reasons we've disabled the hardware
cursor on xf86-video-modesetting altogether.
I've fixed this and submitted it to Factory now. 

The issue can be work-arounded by a simple edit to
/etc/X11/xorg.conf.d/50-device.conf. It is not serious enough to justify an
emergency updated for Tumbleweed.
Tumbleweed is a rolling release, which means that things may break at times -
however it will won't be too long until a fix shows up. the fix will show up
there.
Closing this issue now.
