Bug Description
I have two monitors connected to my Dell XPS 13 via the USB-C output.
For the majority of the time, it works fine. Occasionally, one or both of the images on the displays jump to the right, so that the right few inches appear on the left.
To rectify the problem, I run the 'displays' app, move one of the displays a little, click 'apply', and then, instead of 'keep settings', I 'revert' them to their original, and then everything is fine for a while.
