Unreadable tooltip text

I have this problem with tooltip text. They are unreadable. All other texts are normal.


Anyone knows what could be the problem?

I think there’s some issue with how it processes tooltip text with different systems/GPUs/drivers. I would try messing around with the font size DPI and/or text anti-aliasing in the system panel of user preferences. An updated version of Blender or GPU drivers may help as well. Good luck!
