[6.0.1 build 100.g575f65f40944] Strange bug - viewport zoomed in, can't zoom out

I’m running into a strange bug where, after launching tracking (EDIT: happens after scrubbing too, not just tracking), my viewport zooms in to what seems like 100% (not sure) and stays there. The only workaround is to switch workspaces (eg. Classic to Essentials), but then it happens again next time. Clearing cache does not help, only a computer restart does.

Screenshot of what it looks like:

As opposed to what it should look like (and what it does look like after switching workspaces):

Platform: Windows 10.0.18362.175, Intel i7-4790K, 8GB RAM

Are you working in Linear space by any chance?

Also try turning OFF your zoom window. It’s possibly your zoom window has been made large and is blocking your actual viewport.

I am working in linear space - and turning off my zoom window does not help.

Sounds like we will have to delete your program preferences then, as something has gone wrong there. It looks like you are on windows, so you’ll need to exit out of Mocha and any other programs and then edit your registry keys to do this.

  1. Open Regedit.exe on windows
  2. Navigate to HKEY_CURRENT_USER\Software\Imagineer Systems Ltd
  3. Delete any entries under the above heading.

When you restart Mocha, these should repopulate back to factory defaults. That should reset any window resolution differences.

Cheers,
Mary
