Hi, I have big problems with Big Sur 11.2.1 performance on Macbook pro 2019 32gb ram with Radeon Pro Vega 20 4GB.

Everytime I have open Microsoft teams and Phpstorm and Chrome and switch between these programs after hour or so, GUI starts to stutter and freezes for random time of seconds. Rest of computer works fine for example during call I can still listen and speak without problems just gui is frozen. I experience these problems on whole Big sur line. Every single version was doing so. If there is any other way how can I send you more info, please let me know

On version 11.2.0 I performed complete clean installation.

On my previous laptop under catalina (MBP 13 2018) I never experienced such problems.

I now that Apple wants to promote their new M1 chips, but it's absolutely unacceptable that computer, which I bought for 4000 dollars, had such problems.

Same issue here. Been tracking for a while. Worked fine for something like the first year or two I had the computer, then started happening after an update, I think to Catalina or Big Sur. It only happens when I screen-share in Team, Meet, Zoom, pretty much any of them. Or at least that's what I've correlated the issue to. After over a year of messing around with trying to fix the issue or find resolutions online, I finally gave up and picked up a new M1 MBP for work. Recently, figured I'd give Bootcamp a shot on the I9 Vega Pro 20 to do some Solidworks and gaming. Epic fail. Stock drivers or bootcampdrivers.com version give stuttery performance to the point of unplayability with pretty low settings on games as easy to run as Fortnite (which runs fine on a 2-year older iMac at higher settings).

So, I'm starting to wonder if there isn't a hardware issue with the GPU - and it looks like I'm not the only one having it. If anyone has seen a resolution, I'm all ears. There's nothing I'd like better than to return this expensive machine to active service on other than just menial tasks.
