Tested and it works for me on Windows 7 without a HighDPI system. @tmssngr do you mind testing http://download.geany.org/snapshots/geany-1.34beta1_setup.exe and http://download.geany.org/snapshots/geany-plugins-1.34beta1_setup.exe? They have the suggested change incorporated. If it works as expected, we could prepare a PR for the change.
