[Qgis-user] Problem reading QGIS menus or tool tips in Ubuntu MATE

[Richard Duivenvoorde]

QGIS, in the end, delegates the creation of Tooltips and Menu's to the Qt-Toolkit.

The Qt-Toolkit then has different implementations to actually draw those, depending on your Operating System.

I'm not familiar with Ubuntu MATE, but maybe it's not fully supported by Qt? In other Linux distro's there are often different themes/window managers to choose from, would that help?

Ubuntu to me is well known as "the company who tries to know better... and give up after some time"...

Is there a special reason to NOT use Gnome as desktop? I'm in favour of diversity, but I think as we (as linux users) are already a minority, we should try to focus/support on not too many flavours.
( I'm OK with KDE/Kubuntu too :-) )

Sorry to be not more helpfull, maybe other MATE users have an idea?

Regards,

Richard Duivenvoorde

PS, googling how MATE differs from Gnome I found: https://itsfoss.com/which-ubuntu-install/
It's based on (OLD!!) gnome2... Please give the new Gnome a try, it's my daily driver for years now, and I'm very happy with it

When I switch to a dark theme the menus are okay and I can read them, they have light text on a dark background, but when I hover over an icon the tool tips have light text on a light background and are therefore illegible. The opposite problem occurs whenever I switch to a light theme.

I have tried changing to several different themes in Ubuntu MATE, opening and closing QGIS after resetting the theme, rebooting, trying in a different computer, looking to see if I can find any settings to fix the problem, upgrading QGIS from 3.22 LTR Białowieża to 3.26 Buenos Aires, searching web forums in case somebody else has the same problem and a solution is already known.
