UPDATE and found my personal solution after half a year...
Now, on Big Sur 11.4, in July 2021, I was still annoyed by some level of choppiness of the UI, especially while running on the Intel GPU. For example, I had noticeable lags while typing in Pages, as if this great Laptop was seriously to slow to process simple word processing. Don't get me wrong, everything usable in a decent way, but with micro stutters and little hiccups on a regular basis. On top of that, battery drained 50% in 2,5 hours working in Pages with some background Apple Music running, nothing fancy - to much for my nerves, knowing I spend 3,5 grand for this machine not even a year ago ...
So I looked into it, and found out that the screen saver was taking some amount of CPU-time. Not much, like 3-5 % of total CPU. This, of course, without it being active, because I was using the system. I had this switched on all the time because I use remote access from an iPad often, and sometimes the system would have long idle times.
So, I decided to switch the screen saver off to test this out and guess what - my MacBook Pro 16 inch went instantly back to snappy UI handling. No issues anymore with Safari browsing, typing in Pages and so on. Felt like o.g. Catalina for me, especially on Intel GPU. Finally.
Long story short, give it a try - switch screen saver off. Worked for me.
Wow! @Sherman13's solution worked for me, too. I have an older MacBook Pro Retina 15" mid-2014. Turning off the screen saver seems to work wonders. Thanks for the suggestion, and hope this helps someone else, too.
Never would have guessed this but it worked! Thank you so much, I can keep using my MacBook Air (Early 2014). Wondering what went wrong during development that such a weird bug is present in the system
This worked for me - thanks!

Add a CommentI'm glad it's not just me. Was beginning to think there was something wrong with my Mac. I bought the i9 iMac and really spec'd it out; built to order. But on Big Sur I get stutter animations. If I slowly move my mouse around the cursor is jittery. Almost like it's a bluetooth error but I know it's not. Watching videos and some of them will stutter too. Scrolling stutters. I have to shutdown my computer and restart to clear it up.
And my Apple Wireless Keyboard is not wireless anymore. I have it plugged directly in with a lightning cable because trying to type on it wirelessly would lag and mess up.
This is pretty ridiculous. I hope macOS 12 fixes this.
It works! mcbkpro 13 late 13 2.4 i5 8G ram BigSur(unfortunately)
iMac (Retina 5K, 27-inch, Late 2015) 3.2 GHz Quad-Core Intel Core i5 32 GB 1867 MHz DDR3 AMD Radeon R9 M390 2 GBThe 11.5.1 update caused video/trackpad stuttering. I also lost my directly-connected Dell monitor (iMac thunderbolt to Dell DisplayPort) video. Turning off the Dell fixed the stuttering. Moving the thunderbolt connection from the iMac to my CalDigit hub fixed the second monitor issue. Is it possible to update or reset the iMac's thunderbolt port? I've reset the PRAM so far...
