MacBook Pro M3 Pro GPU micro-freezes with Sidecar

GPU crashes while working/gaming and having Sidecar on – in reality there is a micro freeze for like 1 sec and everything works as normal. I'm not sure if the issue is related to Sidecar or something else, but so far I tried running Apple Diagnostics (no errors), running Cinebench and Geekbench to stress the HW a little bit to see if it's HW fault (seems not). The first occurrence was when I was playing Warcraft, then today when I started working and migrating DB data from one Docker container to another it froze for a second – I checked the log and there were the messages you can see below.

I'm using MacBook Pro 14" with M3 Pro, 36 GB Ram, running latests Tahoe 26.3.
