Cinnamon Serena sometimes freezes when switching display modes

[jjaakkol]

I have a dual monitor setup on HP laptop with a dock with Ubuntu 16.04 + Mint Cinnamon. Pretty often (like 25% of times) cinnamon freezes when switching between laptop internal monitor and dock external DP monitor. Only mouse still moves, cinnamon fails to scale the display and no windows can gain focus. Restarting cinnamon fixes the issue (but you off course you cannot do that in the frozen session). This issue is not new for me, Cinnamon Sarah had it too (I updated to Serena in the hope that it would fix this).

Since I can reproduce this easily, I attached the backtrace of the hung cinnamon process (all threads). However, I suspect the hung thread is thread 1:

I am having the same issue on my Intel NUC with 3 monitors. Two 1080p and one 4k monitor. It gets really annoying really quickly!

This is the same issue. #6314

This might be a dupe of #6224?

@jjaakkol, is this still an issue in Cinnamon 4.2?

[Vahan86]

@icarter09, can we close the issue since there is no response from OP?
