Not sure if it is hardware, or gnome 3, or wayland, or something else, but I notice that in gnome3/wayland after the machine has been running for a bit I get periodic frame skips. It’s noticeable in when I move the cursor around. There is a sub second hang and then the cursor jumps to a new location. Also noticeable when watching video. This happens with an older librem 13 and the librem 15 v3. Need to test with other window managers and without wayland but curious if anyone else has seen this issue or know what could be causing it. Also this is the latest pureos.
This sounds a lot like what I’m seeing:
Mouse Tracking ‘Laggy’ on Wayland, and mouse movements cause frame drops in other OpenGL applications
I’ve seen this almost since day 1 when I bought the Librem 15v3 in March 2018. The bugzilla.bnome.org bug thread started on 2015-02-23 and continues through 2018-09-13, so this bug is almost 4 years old (3 yr, 7 mo) and is still not fixed.
Apparently the system components are interrelated in such a complex way that it’s difficult to isolate these bugs. So, what’s the prognosis? Another year, 2 years, or another 4? It’s tough enough to have a laptop with these instabilities, but at least at the office I have a couple of backup computers. I can’t realistically consider using a phone that’s this unstable. Maybe Purism needs to reconsider using Wayland until stability is achieved. Canonical reverted from Wayland to Xorg for Ubuntu 18.04 LTS because of Wayland bugs and instability: https://www.omgubuntu.co.uk/2018/01/xorg-will-default-display-server-ubuntu-18-04-lts
I’m seeing the same thing after an update. The whole screen will hang for a quarter second every second. This affects videos, navigating with my mouse, pretty much everything. Did anyone ever find a solution to this? It’s really annoying to have to restart my laptop every time this happens.
I noticed I had an old version of coreboot, so I tried upgrading. I’ll let you all know if it fixes the issue.
Nah, upgrading coreboot doesn’t seem to help.
Since 1 or 2 weeks i’ve got a similar problem with my 13v3. Frame skipping could be the right word or flickering screen. It happens from time to time out of nowhere. First i wasn’t sure if hardwarewise something became lose, but right now i’m pretty sure it was introduced with an os-update.
I’ve been logging in with System X11 instead of Wayland GNOME and that particular issue has gone away. You can do this on the login screen (not the decryption screen) after boot by clicking the gear icon under the password field. I have a couple options in my menu: System X11, GNOME, GNOME on Xorg, and Kodi. I don’t know what Kodi is, but I know the only one that’s been stable for me (more or less) has been System X11. I’m pretty sure regular GNOME is Wayland, so definitely avoid that one if you’re seeing this issue.
I’m having some other issues too at the moment, but I’m not sure that they’re related. Hope that helps.
