I was using elvui in 5.2 - not a single problem. But after I updated it for 5.3 I have two problems:
1. Every system announcement [like blabla has come offline, or invite messages] is duplicated. One with timestamp, one without
2. On my shammy when I'm pressing the healer unit frame set - it just sets it like for rdps with all bars on the bottom and raid frames almost at the center of the screen [a little to left]. I don't know why this happened, before I had a nice clean raid frame under the player and target portrait.
