Since "upgrading" to kubuntu20.04 the arduino IDE starts with such ridiculously small menu fonts (4pt?) it is unusable.
Obviously any menus that might influence the font size are also unusable if they exist. Nothing in the system fonts appears to fix this. All other applications seem fine. Same result 1.8.9 and 1.8.13. It's quite annoying, I'm sure there is a simple fix but it eludes me (and clearly shouldn't be the case).
