Re: Extremely small IDE graphics (icons, wires, FP, etc.)
There is actually a sort of a workaround, which is to use run_scaled (see e.g. https://wiki.archlinux.org/index.php/HiDPI#Unsupported_applications , https://ubuntu-mate.community/t/workarounds-for-apps-that-dont-support-hidpi/15875 ).
I still have to get fully around it, but it has potential. My current issues are sometimes random location and spurious window decorations for popups (e.g. menus, tooltips), and honoring english rather than my default hebrew keyboard mapping.
