Things may have changed since I last checked, but when I did a naive “just attach OpenGL” to try and solve the crappy resampling in Windows it made no difference. It was however an awfully long time ago and 2 major JUCE versions since I checked this, so perhaps it’s no longer the case. Or of course it may be that I was making a mistake somewhere along the line. In the end I decided to use the AVIR resampler that’s in @RolandMR’s Gin module with a simple hand-rolled caching solution.
