[Pkg-owncloud-maintainers] Bug#1109392: nextcloud-desktop: Unable to read error message text when using dark theme

[Hefee]

Control: tags -1 + upstream

Hey,

thax for your bugreport. It is a know issue upstream.
Plasma Desktop is not affected by it.

A  workaround is to use another platformtheme. 
Run nextcloud-desktop with an environment variable e.g.:

QT_QPA_PLATFORMTHEME=gtk3  nextcloud-desktop

(replace gtk3 with kde, breeze etc.) [1]

Regards,

hefee
