Cura 4.x.x Slow?

[Travis7s 26]

Has anyone else noticed how slow and sluggish version 4 of Cura runs? I went back and installed a copy of 3.4.1 to test some things today and was blown away by how quick it runs on my system. On 3.4.1 a job sliced in 5 seconds whereas the exact same job on 4.2.1 took 21 seconds. Just navigating the menus and settings on the new Cura has significant delays as well.

I used Cura 4.1.0 for a while now and everything was fine. Later I installed 4.2.1 and 4.3.0. These versions are barely usable. I now have all these three versions on ONE Computer. Cura 4.1.0 is still fast. The younger versions are not.

 

Startup, slicing, everything is slower. Moving the viewport in preview is a real pain.
