Gnome QT render problem after the update

After the latest release QT apps aren’t rendering properly. I used kvantum theme to apply different theme. But it behaved same.

  • background doesn’t apply dark mode.
  • Text is not visible [As shown in screenshot]
  • Applying white theme in Kvantum also doesn’t help.

Is there any fix for it?

A temporary workaround was reported here for light themes.


A temporary solution is to set ‘KvGnomeDark’ theme from kavantum manager. It fixes the font problems.
