I’ve had this issue for a long time with Pro-C 2, and after upgrading to Pro-C 3 the problem still persists, so I thought it would be worth reporting here.
When using Pro-C 3 in Logic Pro, there are various UI scaling and resizing bugs. The plugin sometimes opens at the correct size, but after closing and reopening it, a scaling issue appears where the interface becomes extremely large and occasionally unusable. The only workaround is to reset the UI size by switching between Small / Medium / Large.
