Tearing / sluggish desktop since recent 18.04 update

Asked by Mike

So I did a full update of my system which has been running 18.04 since the beta 2 update and I've noticed now that the desktop feels quite sluggish. The last update I did was about 3 days ago. I'm not sure which package was the culprit as several were updated (30+).

However - I think it has something to do with Gnome. I have a 75 Hz monitor, and it seems like Gnome animations, as well as just actions like moving windows around, feel like they're rendering at a lower frame rate. There is a lot of jitter too almost like tearing.

Moving the mouse cursor around feels like 75 Hz though (super smooth), as well as when I play games. It's really odd. Had no issues prior to running 'apt upgrade'. And I can confirm my monitor is running @ 75.

Is anyone experiencing the same?

System specs:

Threadripper 1950X
64 GB RAM
Radeon Pro WX7100
LG 38UC99 monitor (3840x1600 res).

Description: Ubuntu Bionic Beaver (development branch)
Release: 18.04

I suggest you report a bug. Bionic is not ready and not stable

You could try booting an older kernel. Add the results of your test to the bug report.

Can you help with this problem?
