I can see the LibreOffice Calc auto-filter values, but the moment my mouse leaves the little expand-triangle the selector disappears, making auto-filter unusable. This only happens when fractional scaling is enabled on with my 4K monitor. Is there a setting that fixes this, or a workaround?
Ubuntu 20.10, GeForce GTX 1050, mvidia-driver-455
Upgrading to 21.04 fixed my issue.
