GIMP 2.10.32 running on macOS (Ventura). When full screen/size GIMP becomes unresponsive. If a reduced window is used it mysteriously returns. This behaviour suddenly started only a few weeks ago. I tried earlier GIMP version .dmg files but they acted the same. I thought maybe it was a Ventura bug but I've since discovered that this has actually happened on previous Mac versions going back some time. At least there's a workaround, but it's weird to just start happening though. So, if it happens to you a now you know there is a workaround.
