I open every program through thunar, qt theme is not applied
For example, I open any video with qmplay2 program, qt theme is not applied
In general, I open every file through thunar, which is related to qt(vlc,keepass,qmplay2), and the settings of the qt theme are not applied
But when I open it through the menu, the qt theme is applied
Of course, firejail is also for installation
Does anyone know where the problem is?
Yes, it’s firejail.
