Hello,

I have a Lenovo Legion 7 15imh05 with intel i7-10750H running the intel uhd graphics driver v 27.20.100.8783. I have noticed that desktop windows manager process (dwm.exe) starts to consume a very large amount of memory as time passes (over 3 gb). Once I downgraded my driver to version 27.20.100.8336. The problem is gone. So I think that there is a bug with versions newer than 27.20.100.8783. Is anybody else experiencing this issue on lenovo laptops or other brands running the same graphics driver? And is intel aware of this bug and working on a fix?

 

Problem is present till date 6th November 2021.
