Does this work if you turn on prime sync? i.e. using kernel parameter nvidia-drm.modeset=1 In case of Ubuntu, you might have to add a file in /etc/modprobe.d/ containing options nvidia_XXX_drm modeset=1 with XXX being the major version of the installed nvidia driver. After that, run update-initramfs -u

This is also reproducible on Asus X705UQ (nvidia 940MX). Turned on that parameter and checked with: [code] root@endless:~# cat /sys/module/nvidia_drm/parameters/modeset Y [/code] Started X, set 90 degrees rotation, and the behaviour is still as above.

The display on these laptops is done via the Intel display controller. I checked and this appears to be a bug in xf86-video-intel. Switching to the modesetting driver makes the problem go away. Probably not an nvidia issue then - sorry for the noise
