Hi, I'm running into an issue with mouse stuttering. When I have my 5k monitor hooked up running DP mouse will stutter. When I use my HDMI cable for 4K no stutter.
It's puzzling me because when I install my RX 580 and run 5k with DP cable no stuttering issues. It's only happening with my 5700 XT. In windows, I've had no issues with this card.

System Specs
Ryzen 5 3600
MSI X570 Gaming Edge Wifi
Samsung 960 Pro 1TB
Monitor Planar IX2790 5K
Monitor LG Ultrafine 4K

Things I've tried
different DP cables
Catalina 10.5.5 beta 3
switching to the different PCI-E slot
reinstall macOS 10.5.4
different Kext configurations, tried radeonboost kext no help
tried with my 5700 XT in an Intel Ivy Bridge Hackintosh setup, the same thing would stutter only in 5k resolution but the RX580 runs it fine at 5k.

Any help would be appreciated.
