Research direction
Start by reproducing the HiDPI behavior for Windows VSTs on the listed mingw, msvc, and Ubuntu 24.04 environments, comparing the passing mingw result with the failures. Trace the VST hosting and display-scaling entry points used in those builds. Done means VST interfaces honor the display scale consistently across the failing platforms.
