I downloaded the AppImage of Basic Fresh 7.3.1.3 today and was surprised that it no longer renders in properly on a HiDPI 4K monitor. The window frames are larger than before, while the window contents are smaller than before. I never had to make any adjustments in older versions, and did not see anything obvious way to adjust this in the current version. I’ve revereted to 7.2.5 and it works fine.
