Plugin GUI scaling on high DPI displays
I'm running 5.12 on Linux using high DPI displays, a MacBook retina display and a small 4k monitor. The UI of Ardour itself scales perfectly. From my initial testing, it seems like the native UIs of plugins run at a fixed resolution, and it doesn't seem possible to scale or maximize them, regardless of plugin type (vst, lv2, etc.). An example of this I've tested is the plugin Dexed. Helm, another synth plugin, has similar behavior, and interestingly, its standalone version will indeed scale itself to fit a maximized window. I haven't looked at the code yet, but it seems like it should be possible to allow this kind of scaling inside Ardour. Is this all expected behavior for the current implementation or am I just missing something? I'd appreciate a counterexample plugin that will scale if someone knows of one, just so I can figure out exactly what's happening.
