4k Monitor Support is Missing

[Lonnie Lee Best]

Someone needs to buy the developers of LMMS some 4K displays, so that they'll understand how small the user interface is to users with 4K monitors:

The UI is too small on 4K monitors. In Kubuntu 20.04, my other applications scale up to accommodate 4K, but for some reason LMMS does not.
