Some advice for everyone trying to reproduce this bug https://youtu.be/5Aq2GZpKkLU
Log in a second user! Yes, you can reproduce it with just one logged-in user, but it requires many, many more windows.
(Also try a wired USB mouse, if you can. But the second logged-in user is the important part. It makes it MUCH easier to reproduce.)
@a6ff0b2b Does it get easier as you add logged in users?
@a6ff0b2b not a Mac expert but years (decades?) ago I used to see these symptoms on windows machines with low VRAM. Is it possible a change was made in Mac OS where the second (background) user’s video ram stopped getting released? I can imagine a large percentage of users could see performance GAINS and faster user switching if the second user’s VRAM was still held in memory.
Can’t reiterate enough how much I’m NOT an expert 😅
@a6ff0b2b With one user on an M1 MBP with 32GB of ram, I barely start to feel it around 180 TextEdit windows (in addition to about 20 others spread across several spaces). It definitely increases as I get closer to maxing out TextEdit's 275 windows.
The jumpiness while dragging close to another window is more apparent than the molasses feel. Rather than dragging through molasses, it seems more like it's just dropping frames for me.
@a6ff0b2b We need an audit of windows visibly open - does anyone at Apple, NASA, MIT, The Illuminati, have more than 25 windows open?
