Never heard of the memory leak problem on BigSur. No concerns about stability and memory usage, or at least I've never used to face them on the BigSur.

I have seen someone posted the WindowServer occupying about 10GB memory and thought that's a memory leak.
 
10GB would certainly be a leak. On my machine, it's 1.54GB at the moment, and that's with a few hundred browser tabs and a bunch of other windows. How much is it using in your machine?

I'm running Firefox, VPN, Mail, Messages, and two Windows 10 VMs in Parallels (Outlook plus 3-4 apps in each VM) and WindowServer is using 250MB. Haven't noticed any memory leaks the entire time I've been on Big Sur (2019 15" Core i9, 32GB, 1TB, Vega 20).

I'm still on Catalina 10.15.7, 15-inch late-2013 mbp. WindowServer uses about 1.7GB with about a dozen of pdf files and thirty more firefox tabs.
 
I'm upgrading my M1 mini to Big Sur 11.6.6 right now. It's taking quite some time to do the update. I will see how it goes for a week and then update my 2014 iMac 27. I have had the memory leak issue on my 2014 iMac running Big Sur but not on my M1 mini. I have a peculiar network problem on both machines and also on a 2021 MacBook Pro running Monterey. I have not seen the network problem since updating to Monterey 12.4 but it's only been a week.

The memory leak problem was apparently from a backport from Monterey as I didn't have the problem for a while and then it appeared. It will take me a week to determine if the network problem is fixed as that's how long it usually takes to see it. I was quite tempted to go back to Mojave on the 2014 iMac.
 
Network was down on my M1 mini this morning. I checked all of the cables and still down. I rebooted and the network was there. Strange behavior. I will monitor it for a while. The system was up for 10 days. I see that there are some other reports of network issues. I may try the workaround of using WiFi if I see the problem again.
