Unresponsive GUI after update (KWin is unstable)


Hi all,

Two stock Dragonboard 820, running Linaro.
After apt dist-upgrade and reboot, GUI is completely unresponsive and the following message appears after a while:
KWin is unstable
It seems to have crashed several times in a row.
You can select another window manager to run.

Has anyone encountered this issue?
Any idea on how to solve it?



Does the following help:


Thank you so much, it worked perfectly!
These commands did the trick:

sudo apt-mark hold linux-image-4.14.0-qcomlt-arm64
sudo apt update
sudo apt dist-upgrade
sudo reboot
