Sync is off,
I have some extensions, like vpn, elementhider and one that manages tabperformance, but both shouldnt interfere.
I think all the scenarios said can cause things like this to happen, I rather update this message later.
Usually its when I use 2 browsers and have a lot of tabs open, but since my Orion freezes a lot, I switch a lot to Safari before it appears.
I think 1 window is affected, but when windows talk to eachother, like creating a new one, it makes mistakes too.
I usually ignore the state, or force quit all windows.
Like I stated in other threads, I have a M2, OS 26.1, Low on Ram & Disk.
