When did you last update the OS?
Edit: Before doing a reinstall, I’d make a new user account to see if it’s happening there first. Reinstalls are a last resort as there’s no going back with it.

Based on some quick research into this, the windows are likely jumping sizes because of something like a stuck key, a shortcut, the hot‑corner, the graphics driver, or the compositor being triggered unintentionally. I’d say you should first test for any stuck keys that could be the cause (IE: Super, Alt + F10/Space) with xev – multiple events = sticky key. Or you could just plug in an external keyboard and if it stops, the built‑in keyboard is at fault.
If stuck keys aren’t the issue, try turning off hot corners + window tiling in the settings, then restart the device. If it’s still happening after this, checking that you’re using the correct graphics driver would be the move. You can run inxi -Gx to adjust the driver.
If none of this fixes the issue, peep the recent updates in /var/log/apt/history.log for any packages which were recently updated that could cause the problem. You could also make a fresh user account to see if the problem is system‑wide or confined to your config. Once you find and correct the trigger, the flickering and whatnot will stop, you just have to figure out what’s causing it.

As someone with a few autoimmune disorders, the most effective way to assess a doctor is to see if they talk with you or at you. If they talk at you during the first appointment, it’s best to cut em loose and keep looking until you find one who talks with you. This, along with having a decent knowledge base of the topic at hand, prevents you from having a power tripping M.D. and also makes getting proper medical attention much easier!
