I have an external monitor with a lower resolution than my MacBook. I primarily work on my external monitor, but occasionally open the preview function to test my screens on a smaller display.
- opening the preview feature (cmd+P)
- move the window to MacBook display
→ the screen is displayed at half size
Workaround:
- closing window and reopening doesn’t work (preview window always opens on the display where sketch is running)
- enter full screen/close full screen does work (but is pretty annoying)
Unfortunately, I can’t remember when the issue first popped up for me. Maybe a quarter to half a year ago. But I know that it used to work.
