BPM display problem in rekordbox

Hi everyone!

I've been searching the forums and videos and tried everything to solve it, none has worked so far...

I run the latest rekordbox dj with ddj-rb and my bpm display looks like this:

other texts may also partially disappear sometimes.

I reinstalled rekordbox, tried changing view settings and also redownloaded and reinstalled all fonts.

I run it on Win 7 64 bit.

I'd love to resolve asap!

Thanks
