With the recent hiDPI support changes things have gotten a bit better looking, but some things are still broken. This is on Windows 10.
If you open AudioPluginHost on a hiDPI screen (I assume anywhere where scaling factor is not 1) and try to open the UI for any of the Arturia plugins like Wurli (or any other Arturia V or VI collection plugin)- it comes up with the container window scaled x2, but the plugin itself is not scaled. The menu for the plugin is scaled, but invisible until one blindly clicks in the upper left corner (see picture)
This is for both VST2 and VST3 versions of these plugins.
Regular DPI screens work, but this is a fairly big issue as more and more devices come with or use hiDPI screens.
I tried opening these in Cakewalk for example and they show up perfectly fine on the same machine.
I noticed a hack for “Kontakt” in the plugin window class which does not disable the the DPIAwareness, but that results in a different behaviour.
I’m sure that there are other plugins with similar issues. Is there any chance a “hiDPI expert” can take a look at this ? I can help with anything that needs testing or trying out.
