When I run my Plugin in the VST3 Validator by Steinberg, the validator which usually needs a few seconds for all tests gets stuck for a frew minutes at:
[Process function running in another thread]
Info: ===Process function running in another thread ====================================
after the time it took to do this test the test succeeded, so I have no error to find…
I dont have any other DAW or plugin host opened where the plugin could be running in.
Afterwards, it also gets stuck in
Info: ===Silence Processing ====================================
Edit: the plugin also passes every test in pluginval with strictnesslevel 10
Edit 2: use AudioBuffer::makeCopyOf instead of copyFrom for correct buffer sizes if you encounter this issue.
