Sorry Sebastian - I didn't relaise journalctl piped output to less!

This is visible on the login screen and once logged in. Only the "shell" is corrupted and any subsequent changes, such as changing the background image, are displayed without corruption. The corruption is random but it is predictable that it will appear on the launcher icons, background image and shell menu icons and text. I've tried swapping between available graphics drivers but it makes no difference. Text corruption in menus is on particular glyphs selected at random. In the screen shots, for example, all upper-case and lower-case 'O's are currupted but on a subsequent reboot the affected glyphs will vary. On filing this bug I also notice that the pop-up modal password requests also displayed the corrupted glyphs. No programms run subsequently will display any problems.
