Applications like WPS office Spreadsheets and Matlab Simulink library become unreadable because content within windows is forced black which text, dividers etc remain black. The theme should not affect those components Reproducible: Always Steps to Reproduce: 1. Apply Breeze dark theme 2. Open WPS Spreadsheets/ Simulink 3. Actual Results: The Spreadsheet area is black (Slate) as per the theme. If I change the color scheme the background can be changed too Expected Results: The theme should not apply to that part of the application. I haven't seen this on other desktop environments Kubuntu 16.04 with Plasma 5.6.5 (Updated via Kubuntu backports)
That's almost certainly a bug in their applications. If they cherry-pick what theme parts they load (and do it badly) there's not a lot we can do. Any idea what toolkit those applications are written in?
Fair enough, I just hadn't seen it in Gnome when I was running Fedora. They don't really mention what toolkit they use, however their development page mentions a modified version of Qt, so perhaps Qt. http://wps-community.org/development As for MatLab I can't say
You might find unsett XDG_CURRENT_DESKTOP will force it to not try and load any KDE settings and hopefully fix it. Other than that I'm afraid we can't do much. Sorry.
