--- Comment #20 from Michael Setzer II mikes@kuentos.guam.net --- Just going to give up on winehq-devel. Tried lots of things, but nothing seems to work. The new 10.10 has same problem on that machine, and now on other machines the 10.10 totally screws up the one windows app I use. So, I've just moved all machines to winehq-stable.
Opened another bugzillia with the issue with Pegasus Email screen going totally screwy with 10.10.
Posted to Fedora bugzilla since the regression page seemed to be apt centered rather than dnf. so didn't get far with it. Then they just replied not a Fedora App so go to winehq.
Was interesting to try and find issue, but got nowhere.
