[SOLVED] Colour display problems in text of Global Menu widget (Kubuntu Backports)

[Schwarzer Kater]

Dear fellow Plasma and Kubuntu users,


after upgrading Kubuntu 22.04 with Kubuntu Backports enabled (ppa:kubuntu-ppa/backports), a colour display problem in the text of the Global Menu widget occurred:
If I use a dark Plasma style (e.g. Breeze Dark) in combination with a light colour scheme (e.g. Breeze Light or Breeze Classic) the text of the Global Menu widget is displayed very dark, nearly unreadable. This combination is the default setting in Kubuntu and I have liked it for many years.
If I use a light Plasma style (e.g. Breeze Light) in combination with a dark colour scheme (e.g. Breeze Dark) the text in the Global Menu widget appears very bright, also nearly unreadable.

It makes no difference if I use the Global Menu widget in a Plasma panel, a Latte-Dock panel or the Application Menu Bar.







I tested this behavior of the Global Menu widget in different distributions, and only in Kubuntu 22.04 + Backports it does not work properly:

Operating System: Kubuntu 22.04 + Kubuntu Backports (ppa:kubuntu-ppa/backports)
KDE Plasma Version: 5.24.5
KDE Frameworks Version: 5.94.0
Qt Version: 5.15.3
Kernel Version: 5.15.0-33-generic (64-bit)
KDE Gear Version: 22.04.1

-> Colour display problems in the text of the Global Menu widget with Plasma panel, Latte-Dock panel and Application Menu Bar - both tested in a "clean" install and a Kubuntu 22.04 upgraded from 20.04 to 20.10 to 21.04 to 21.10 to 22.04. Of course I created a new additional user, but the problem seems to have nothing to do with $HOME either.

-> OK, no colour display problems - there is no Plasma style to choose from at present, but you can test it by changing the global design to "Breeze Twilight".


Any ideas how to fix this?

After today's update from the Kubuntu Backports PPA to KDE Plasma version 5.24.6 the issue is gone - the text in the Global Menu is readable again (white text on dark background).
Thank you very much! :-)))
