Thanks for your tests and the video. No problem for the video quality as long as it shows the problem.
For interested users, this video shows that the 3D view gets greyed also when a dialog box is opened in the program or when a tool tip of the catalog partially covers the 3D view, like in the following image.
I could reproduce the second issue, but not the first one, but they are similar because actually, the 3D view gets greyed when a sub window is opened, whether this sub window is a dialog box or a tool tip. The good thing is that the 3D view returns to normal as soon as these sub windows are closed, almost all the time. I'm going to check if it can be fixed.
Did you notice at least some improvements about the 3D view resizing?
