Public bug reported: After a regular update of my LTS during the last week, the screen has started showing corruption. For instance, when I maximise a window, the screen flickers for up to a second with an overlay of black dashes and stripes, sometimes in a chevron pattern or just horizontal black dashes covering the whole screen, especially on an external display.
It does not show up in a screen capture.
