LAYOUT - resizing viewport clashes and difficult

I found it hard to resize viewport in the current 2026 version in LAYOUT ( I haven’t used 2025 for as long as I been working with RHINO 3D for a while and it was a bit glitchy for me anyway)

So, recently I found that when I tried to jump form a scale to full size . I have to first double click into the viewport then unclick " Preserve Scale " and then zoom in manually to somewhere close to FULL SIZE. Then click out of the viewport and set FULL SIZE. Otherwise I just end up with an empty viewport. I can unclick "Preserve Scale " previous to click into the viewport , but it is a bit glitchy.

And very often clashes either way.

Not sure if it is a BUG or not. I was wondering if anybody else have problem vit viewport scale and enlarging in 2026.

I used to have problems where if the centre of the SketchUp scene was far from the viewport, things would bug out on me. As in - if the viewport was “resized” a lot. But I can’t be sure that is the problem you are having without a screenshot or two? Or even a file to share if you can. These things can depend on whether the viewport is orthogonal/perspective, how big the model is, how far the model is from the model axes etc.
