Fullscreen acting strange

Hi, for the first time ever I noticed there was a fullscreen button in blender, of course I automatically try it out. Looked neat until I moved my mouse around, whenever I hover over any menu (anything I can click), Everything on screen starts to flicker and some other strange undescribable things happen. Anybody know why this is happening?

btw: I am using a linux debian 8

edit: I noticed when I switch back to the blender default theme it stops, all other themes I tried do it though.

Anybody? Should I just report it as a bug?

sounds like a graphic issue it is possible that your PC does not enough graphic support to run the feature.

Thanks for the answer, my pc is indeed pretty old and bad, I guess I won’t report it as a bug then.
