Pro C3 scaling/resizing bug on Logic Pro
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.

i am seeing this occasionally as well (logic 11.2.2 on mac os 26)...
We'd like to find out more about what's actually happening here since we aren't seeing this problem ourselves so far. Can you please email us at info@fabfilter.com with the following information:
- Description of your system setup and monitor resolutions and DPI (retina yes/no)
- Please attach your preferences file. In Finder, click Go > Folder and type ~/Library. Locate com.fabfilter.Pro-C.3.plist and attach it to your email.
- Screen shot of the plugin within Logic
Thanks!
