It seems that with windows 8.1. (after update from windows 8.0) all applications which doesn't scale GUI, will be automatically up-scaled? (Looks very bad imho.. with 125% which is the automatic setting on my monitor)
Can it be, the juce-Apps will now double upscaled (the good way internally, and the bad way windows does)
There must be a flag that windows recognizes that an application support the current dpi resolution.
Maybe this is a helpful information?
