I need to add UI scaling option to my todo list. You can work around this for now by right-clicking MubLoop.exe, going to Properties -> Compatibility -> Change high DPI settings, and setting ”Override high DPI scaling behavior” to System. The app will scale up, though it may look slightly blurry.
that worked ... thank you very much ... but now the next problem ... Is there a possibility of changing the audio engine? I am hearing a lot of artifacts with your app, and I use normally a ASIO audio driver.
It currently uses WaveOut which can conflict with ASIO drivers. There is no device selection yet. As a workaround, try temporarily switching your default Windows playback device.
