Works good for me. Maybe try updating your system (pacman -Syu).

I of course did. It didn’t help, this is why I created this thread.

$ su -c 'pacman -Syu'

 there is nothing to do

$ openscad --version

$ uname -rms

$ pacman -Qi nvidia | grep Version | tr -s " "

I would try a different wm or de, and see if it it works. Works for me on DWM.

Nah, that’s not the issue. But during testing with DWM I found out that OpenSCAD chokes on UI scaling. Because I have a high resolution screen and X and all the UI toolkits have issues with basically anything greater than 96 DPI I had to add QT_SCALE_FACTOR=0.8 (and some others) to .xinitrc.

Without QT_SCALE_FACTOR=0.8 OpenSCAD and all other QT applications are absurdly scaled up. Since OpenSCAD is the only application that has issues with scaling like that, a quick solution is adding an alias.

alias openscad="QT_SCALE_FACTOR=1 /usr/bin/openscad"

With this the UI isn’t messed up and can be used. This doesn’t fix the absurd scaling, though.

Good job investigating the issue. I encourage you to file a bug: https://github.com/openscad/openscad/issues/

Also, clicking the menus and hovering the options with the mouse cursor ends up in this:
