Thanks, BubbaBlues... I just saw your reply.
I use 64-bit Mint 12 KDE as well.
Did you upgrade from 12 to 13? Or did you do a clean install?
I am thinking about upgrading, but I don't really want to format my partitions again.
Things I'm looking out for are regressions -- like some have posted about a freezing problem in 13... although that might have been just for the Main Edition, I'm not sure.
Also I read a few posts about HDMI not working in 13 although it worked in 12. Is the font problem the only issue you have had? Have you found a fix for it yet?
Also do you use LibreOffice? I'm somewhat hopeful that the KWin updates have fixed the freezing issue. Can you do me a small favor and see if LibreOffice Writer still lags and freezes after you perform a suspend/resume cycle while a document is open in Writer?
Thanks for posting your comments... if I decide to install the RC, can I simply update to final release without much trouble? I've never done that before. --Jim
