@ed95 Here is a video that describes the VST3 plugin size problem. The plugin always scales up and fills the window. This does not happen with the VST2 version.

```

This works if i implement the resizing manually without `setResizable(true, true);` or with the timer solution. In this case the VST3 host probably don’t know that the plugin is resizable and it does not scale up.

The work around with the timer and maybe also the implementation without `setResizable(true, true);` does not work anymore on linux in Bitwig. In this case the host does not scale the window anymore when scaling the plugin.

See here:
