I saw this also, but now I cannot duplicate it, at least not in the development version
Nevertheless, I made a change that I hope fixes the problem. But since I couldn’t reliably duplicate the problem, I can’t say for sure that my change will fix the problem. At least it doesn’t seem to make the problem worse. So keep your eyes open for this when the next release comes out.
EDIT: Oh darn, I was just able to duplicate this again. So my fix did not work. I thought it had something to do with the inspector panel incorrectly appearing, but now I think this might be a problem with elastic windows.
