Indeed, 2 years struggling with this issue (Dual 4K Dell).
Some suggestion for very slight performance improvements (like suggested previously), but definitely still sluggish.
- Disable Hardware Accerate Composition
- Reducing timeline window
- Bringing the timeline window on the same monitor as the preview window (kind of defeats the purpose of DUAL monitor) but helps a bit.
- Changing to HIGH DPI Settings to System > Causes low resolution preview and blurry interface.
- Disable your second monitor (just kidding).
Adobe must tackle the issue. It is NOT an isolated case. I can reproduce the issue on any system with dual 4k monitors. (Tested on 3 systems).
Please ADOBE, conduct a thorough analysis of the UI drawing issue using a complex composition setups and multiple open panels. The struggle is real.
