UI strange behavior

Hello,
I get strange artifacts around working area, see screen grabs below, when using named views.
To clear it, I reduce or maximize the window (opposite of current state).
I tried modify, I tried fresh install and rebuilt tabs, etc.
Any ideas how to fix?
This has been going on since 8/25.
Thanks,
Glenn
