A functionality of Dolphin that I use a lot is the mouse-hover file preview (toggled by the F11 key). I specially like to use it on text files to avoid the trouble of opening them, and up until recently I managed to do so with no problem. However, recently this began to happen:
If you look closely enough, you can notice that the text preview is in there... but the text is white and thus almost unreadable. It used to be black, but now it is always white.
The qvantum theme has always been there, and this problem persists even if I turn back to the normal one.
Is this a general problem in here? And, though I find it unlikely, is there any immediate fix?
