In one of the recent updates, something changed to the minimum width of the plugin windows. Besides it feels weird and awkward now, having my UAD SSL compressor (and a lot of other plugins) in a way bigger windows with just an empty black area besides it, there is also a bug in it.
When I add the Sonnox Inflator, the width of the plugin hits a threshold where it cannot decide wether to make it smaller or wider, and keeps flickering the right side of the plugin window. This is also where the close button is, which is also jumping around continuously.
