I've done a clean install with Windows 8.1 and there are two problems I'm having: 1. The latest Intel drivers for my HD3000 seem to cause some graphical glitches (screen randomly displaying blocks of black, images not being displayed correctly or just being replaced by a solid color image - I blocked out the text in my bookmarks BTW). As I post this, I'm curious if I've noticed it anywhere other than in Firefox, so the problem could be Firefox. 2. In Firefox, the bookmark folder icons are no longer displayed correctly. It worked fine in 8.0. I can't seem to find any other posts about this. (This isn't the same problem as the blurry toolbar icons/DPI issue introduced with FF22 - I've already taken care of that) Has anyone seen any fixes for these issues?
