I believe I may have found a small, fairly inconsequential bug that I sometimes witnessed in DTPO2 and now encountered in DT3. I believe the steps are:
- Open a PDF document in its own document viewer.
- Make that document viewer full-screen, i.e. use the green button to give it its own full screen space.
- Open some other window.
- Restart macOS with the setting “reopen windows when logging back in”.
- The document window should now look like this. The document has been mirrored (not rotated) vertically and horizontally, as far as I can tell:
This should disappear if you close and reopen the document viewer.
I hope someone can replicate! All the best!
