I switched from macOS to Linux about a year ago. I still miss the polished UI and battery life of macOS, but for development, Linux feels much more productive. Native Docker support, better window management, and full control over the system made the switch worth it for me.

This sounds like it could be related to a compatibility issue after the macOS Tahoe 26.1 update rather than a simple mouse problem.
A few things you can try:
* Disconnect and reconnect the mouse, then remove it from Bluetooth settings and pair it again.
* Check if the issue happens with both Bluetooth and wired mice to rule out a hardware problem.
* Boot into Safe Mode and check whether the freezing and screen flickering still occur.
* Update any mouse drivers or companion software (Logitech Options, Razer Synapse, etc.) if you use a third-party device.
* Check Activity Monitor to see if any process is causing high CPU or memory usage after the update.
* Try disabling external display adapters/docks temporarily if you use one, as display flickering and window repositioning can sometimes be related to graphics or display driver issues.
If the problem started immediately after the Tahoe 26.1 update, it may also be worth checking Apple community reports or waiting for a minor patch if it's a widespread bug.
Hope you get it sorted soon — intermittent freezes like this can be extremely frustrating.
