Whonix 14 Strange TorBrowser tab artifacts / ugly GTK theme

After replacing my Whonix 13 with Whonix 14 on Qubes 4, I notice that the TorBrowser has some strange artifacts around the tabs, and in general the GTK theme (such as the file selection when uploading a screenshot into this very post I’m writing) feels ‘ugly’ e.g scrollbars are very ‘blocky’. It looked better under Whonix 13 somehow.

Anyone else noticed this? I didn’t do anything unusual in my fetching of Whonix 14 per the ‘Upgrade’ wiki docs.

Need to adjust the GTK theme somehow to something a bit nicer?

Does this happen also in TBB in a Qubes AppVM based on a debian-9 (stretch!) TemplateVM vs Tor Browser on Qubes-Whonix 14 ((stretch))?

Yes, but that was a Whonix 14 release a few minor testing releases ago. But obviously the issue persists.

Haven’t explored this at all in alternate VMs to see if it is Qubes-Whonix specific. I don’t think any non-Qubes-Whonix 14 users reported this (?)

Probably caused by us disabling desktop effects and the compositor for less RAM usage. I guess the price was ugly GUIs :-/

If you refer to KDE configs - these may not apply to Qubes-Whonix since no KDE gui is installed there.

My bad. I thought only Dom0 switched to XFCE.

Just tried in vanilla Debian 9 with same (latest) Tor Browser. Indeed, the artifacts on the ‘tab’ buttons are the same problem as in Whonix 14!

The file selection dialog is however ‘prettier’ in Debian 9 than Whonix 14. But really it is just the tabs in browser that are most distracting. In any case, seems indeed not ‘your’ problem.

Anyway, the issue does not affect quantum-based torbrowser (8.0a9).


Indeed pleased to see the tab appearance is much cleaner in new TB 8.0 \o/
