Description Maxwell Bottiger 2018-10-22 14:35:28 UTC 
User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
Build Identifier: 

After the most recent round of updates, my mouse pointer now flickers when anything moves on the screen, or I type anything.  It does not seem to be dependent on any particular application, nor does it seem to matter if I have external monitors connected to my laptop.  It is only the mouse pointer that is flickering.  All of the other windows and launchers seem fine.

Reproducible: Always

Steps to Reproduce:
1.Log into a graphical session
2.Move mouse
3.
Actual Results:  
The cursor disappears and blinks often

Expected Results:  
A solid cursor or pointer

I'm using a Dell XPS 2 in 1, 2018 model.  The laptop is up to date, and I see the same behavior in Linux 4.12 and 4.18.

Comment 1 Stefan Dirsch 2018-10-22 14:57:36 UTC 
Hmm. Sounds to me like a kernel regression.
Comment 2 Maxwell Bottiger 2018-10-22 15:03:31 UTC 
Actually, I figured this out.  I had forgotten that I put on the displaylink driver for an external monitor from here: https://software.opensuse.org/package/displaylink?search_term=DisplayLink

I just removed that and rebooted, and now everything is back to normal.  False alarm, sorry.
Comment 3 Stefan Dirsch 2018-10-22 15:08:06 UTC 
Ah! Ok.
