### Bug Summary

If you resize the plugin after a certain point (maybe FHD resolution?) on a 1440p display, the visualizerbreaks and stops working.

### Expected Behaviour

It should resize no matter how big, or have a maximum window size limitations to avoid the user going into it.

### Steps To Reproduce

Get on a high resolution display, like 1400p or 4k, and resize it until you notice the numbers on the right disappear.

Reproduce the New Compressor plugin resizing problem on a high-resolution Windows display, following the reported steps until the visualizer numbers disappear. Locate the plugin's resize and visualizer UI code, then verify that resizing preserves the visualizer or enforces a maximum size that prevents the breakage.
