after last update, it worked for me too ,but my folder number already beyoud 10+ lol ,and cant go back if that number had being used.
I found GM had try it ,they using another resolution solution. But still remain problem. Once you get into full screen mode and back to windows mode, its looking normal now.(in which using new solution achieved this, fix the too small problem in high resolution screen) But if turn client off and try to launch a new one, it is still the same need change folder name like dave said or still same problem like before. In other word, GM only fix this scale problem when your client is running after renew it, all are the same issue.
