- Ubuntu 16.04 LTS i686 Are you really using 32bit?
Yes $ uname -a Linux x2go-i686-vm 4.4.0-79-generic #100-Ubuntu SMP Wed May 17 19:57:27 UTC 2017 i686 i686 i686 GNU/Linux
I'm running all tests on a amd64 machine too, I get the same results $ uname -a Linux x2go-amd64-vm 4.4.0-79-generic #100-Ubuntu SMP Wed May 17 19:58:14 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
- nx set to link=3Dlan, pack=3Dadaptive-9, the rest as default Are you also _running_ on a LAN?
Yes, 1Gbps link 1 hop away from the server for testing purposes. Reduced it to ADSL as a test, artifacts remain.
acceleration disabled and rendering by cairo. How did you disable hw rendering?
Options -> Advanced -> uncheck "Use hardware acceleration..."
Enabling it doesn't make a difference, the artifacts remain. I'm running VMs without any GPU support.
For cairo in about:config
gfx.canvas.azure.backends cairo gfx.content.azure.backends cairo gfx.xrender.enabled true
Have you tried the firefox (53.0.2 or newer, not an ESR version) that Ubuntu is delivering with the distro? Is it also happening with that version?
Yes, current Firefox from Ubuntu repos and the latest 54.0b13 from Mozilla's build have the same issue.
I suggest to clear the caches on server and client and then retry with a new session. Caches are in ~/.x2go.
No improvement.

Artifacts in the chrome seem to disappear when I resize the window and it has to be redrawn. They reappear after I hover on them (ie, after the backgound changes).
as well as some URLs your are seeing the problem with.
A good universal reference is about:mozilla.
Artifacts in the chrome are noticeable in the "+" to create a new tab, for example.
Also I'd like to know the kind of session you are running
Im running Firefox as single application, for instance: /opt/firefox52esr/firefox -P
Is your distro uptodate?
Yes, installed from 16.04.2 Ubuntu ISOs, just updated/upgraded.
In a broken session please post the options file from the server side (~/.x2go/C-*/options).
