Starting Houdini 20.5.332 without any custom preferences or any plugins I can recreate this issue reliably. After a bit of work in the viewport and switching to the Stage context and then back to Obj/Geo context I can get the viewport into a state such that when in any other mode (translate/manipulator/select) the viewport won't switch back to View mode when tapping Spacebar or Alt. I have to mouse LMB-click on the View Icon on the left side. Or, reset the viewport via the Labs menu (but, this is problematic as trying to reset the viewport in the Stage context causes H to hang and I need to restart).


I'm on the latest MacOS (Sonoma 14.6.1), Mac Pro 2019, Intel Xeon W 16-core, 4x Radeon Pro 6800W GPUs.


Any help would be greatly appreciated. Is this a bug? Expected behavior? Might I be doing something I maybe shouldn't or not doing something I should?

Thanks,
Greg

I’m experiencing the same thing on mac fwiw. Navigation in general has always had more issues on mac compared to linux. Not that linux doesn’t have its moments as well of course.

I got a macbook in June and have experienced similar issues, which I do not encounter on linux.

Well, at least three of us has the problem. If I don't hear anything about a solution here I'll file a bug report later today.
