Hi, I'm using an iMac Pro, Resolume Arena 6 latest version (also tried installing earlier versions and the problem still exists).
The Screen that is having issues resolution is 3200x765 from the iMac. The other screens that have no issues are 1080p and 720p.
The screen manufacture and I have worked through a few things, the problem doesn't happen when resolume is closed but does when resolume opens. The glitch is random and no pattern to it and only on the one output when Resolume is open.
The hardware is USB C - HDMI - Sender, but the problem goes away as soon as resolume is closed.
If anyone has any ideas or solutions, love to hear them!
Thanks again for your time!
