UX issue with last driver 1.1.62

[Tang]

Hi everybody

I installed last week latest driver version and i got ux issues as you can see in screenshots.
It happens all the time and it's very uncomfortable.
With previous version i didn't encountered those issues. Switching back to version 1.0.335 didn't fix it.

I'm running debian stable on DELL XPS 13 version 2015.
Linux mp-de-057 4.4.0-0.bpo.1-amd64 #1 SMP Debian 4.4.6-1~bpo8+1 (2016-03-20) x86_64 GNU/Linux
ii xserver-xorg-video-intel 2:2.99.917+git20160522-1~bpo8+1 amd64

Thanks for your feedback :)

Could you attach logs that would tell us more details of your setup?

Hi,

I'm having the same problem - Dell XPS 13 9350 with ubuntu 16.04 with Gnome as desktop environment

DisplayLink device : D3100

4.4.0-24-generic #43-Ubuntu SMP Wed Jun 8 19:27:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

displaylink driver: 1.1.62

I attached my log files.

This appears to be the same issue as I just got. I posted it here:
http://displaylink.org/forum/showthread.php?t=64599
It seems to be a problem with compositors which partially update the framebuffer (only updates changed areas, not the whole screen), specifically MESA_copy_sub_buffer and possibly equivalents. Does DisplayLink do anything special with the mouse cursor?

Edit: this issue also occurs with the compositor turned off entirely. The issue does not occur when telling the compositor to refresh the whole screen constantly (which pretty much kills displaylink performance)
