i3wm significant lag vs. normal ubuntu gnome session

I use i3wm for a couple of years now on Ubuntu. Never had an issue like this one before. I just upgraded to 22.10, but after the update, while in i3wm, I have the following issues:

1. Whenever I open an application, the screen will temporarily tear, showing other (or previous) applications on some parts of the screen.

2. In a terminal there is a lot of keyboard input lag.

3. Emacs is particularly bad, the input lag is horrendous, at one point even looked like the laptop froze for a bit.

4. Actually, the lag is especially bad on any Desktop where I have Vim OR Emacs open. So bad that the laptop actually freezes for about 5 seconds before I can do anything.

5. New Information: I discovered that, on a clean boot directly into i3wm, this lag will happen. If however I log into a normal Ubuntu Gnome session first, then log out of that and back into gnome, then suddenly this lag disappears.

This did not happen on 22.04 (i3wm) and if I log into a normal gnome session this is also not a problem.

Also, I should point out that I did try compton, since some people mention that this might be the cause on other forums... This did not resolve the issue.

Anyone knows what the issue is here?

PS: Do not tell me to use gnome session instead, non-tiling window managers became very cumbersome to me by now and it slows my work down significantly. I would much rather format and reinstall 22.04 and i3wm, than use any non-tiling wm at this stage.

I had the exact same issue, input lag in i3 but not in gnome on ubuntu 22.10.

The solution for me was to upgrade to linux kernel 6.0 or downgrade to <5.19.
