Created attachment 115413 [details] example image showing the description text in menu sometimes appearing as cubes Every so often the description text in the Application Launcher (with "Show applications by name" checked) turns into white/grey squares, and only a logging in and out/restarting appears to fix it. Reproducible: Not always, it seems to happen more often after changing the workspace theme, but it usually happens sporadically. OBSERVED RESULT The description of all applications and names of the menu buttons/tabs at the bottom appear as grey/white squares. Interestingly enough, hyphens appear as normal. EXPECTED RESULT Descriptions of applications and the names of menu buttons should be rendered as normal, with characters appearing as letters, not cubes.

Are you using NVIDIA hardware and proprietary drivers?
(In reply to Nate Graham from comment #1) > Are you using NVIDIA hardware and proprietary drivers? Yes. The card in question is a geforce 1050 TI with driver version 410.57
Almost certainly an issue with the proprietary NVIDIA driver, especially since you're using the cutting-edge 400-series drivers. You might try downgrading to something in the 300-series if it has support for your hardware. Beyond that, you can report it to NVIDIA; maybe they might care.
