Win 11+IPR+ Material Editor=very very very slow

[dongxi_y]

In the win11 system, as long as the material editor is opened, the interactive rendering (IPR) operation will become very slow. (Unacceptably slow) win10 will not be so slow. I hope it can be improved.

I can't reproduce the issue with any of the scenes i tried: the compact mtl editor open or closed makes no appreciable difference to my IPR speed (i'm on Intel, though.).
If you have a scene showing the behaviour, we'd be keen to get a copy of it.

I found a video of this problem in another post, the UI became very slow.

This problem occurs in win11. There is no problem in win10

The issue from the other thread has nothing to do with the IPR speed, but regardless that too doesn't reproduce on our side.
I tried your issue under windows 11 of course, but it still didn't reproduce: IPR (or UI, for that matter) speed is unaffected.
Hence the request, which i renew, for a scene file, or better directions, to be able to see the issue in action on our side.
If we can't reproduce the issue, we can't fix it.

Please test a complete scene. If the scene is very simple and will not appear particularly slow, the real-time rendering will be smoother without opening the material panel. However, when the material panel is opened, the mouse will be very slow to move and become inoperable.
