My PsychoPy startup window is simple enough - it says “Press space to begin”. However, sometimes I need to move the window to a different monitor. When I do that, I need to click on the window before dragging it. When I do that the text disappears, leaving a blank window. Why does this happen? How do I fix it?
Builder or coder?
In code are you using waitKeys() or are you using a draw loop with win.flip() and getKeys()?
It probably won’t show while you are moving it regardless, but on most systems if you are using a draw loop with win.flip() and getKeys() it will at least reappear after you stop moving it. If you are using waitKeys() it stops refreshing the window until the key-press, which seems like it would be a likely source of the issue.
If you’re on a Mac and switching between a retina display and a non-retina display it might still not work but in that case just tell it to make the window on the monitor you want it to end up on using the “screen” argument.
