Summary0009988: checkSizeContraints(size) not called when resizing plugin windows
DescriptionThe VST3 spec says that checkSizeContraints(size) should be called when a user is resizing a window by dragging. This is not the case, which results in an issue for FabFilter plugins. These plugins store the width and height in settings on disk. Those settings are read on startup and used for minimum size of the plugin window.
Steps To Reproduce- Download for example Pro-DS on the FabFilter site https://www.fabfilter.com/download#download-pro-ds-de-esser-plug-in and install
- Open Ardour and put Pro-DS on a track
- Resize the plugin to be larger than the default
- Close Ardour
- Open Ardour
- Open Pro-DS
- The plugin window can not be resized to any size smaller than the previous size, which is stored on disk.
