BUG: Viewport capture incorrect scale while unlocked

Rhino Rhino for Windows
1

I noticed that when I lock the viewport, it will produce proper scale for the viewport capture. However, once I unlock the viewport, some bug happens and the scale of the captured image is noticeably smaller.

I use a 4K screen resolution (3840 × 2160 pixels) with 200% scaling in Windows 10. I also capture my images with a custom resolution for A4 paper format multiplied by 2 (I use 1920 x 1080 from the dropdown list due to the lack of a proper 3840 × 2160 option). Either the scaling by Windows 10 of from the capture pop-up window causes some interference with the screen capture function of Rhino.

Is there anybody who could replicate that bug on their Rhino 7?

Hi,
here I can reproduce it, although the difference is much smaller and it happens in R7.36 and R8.6
My screen resolution is 1920x1080 with 100% scaling

That’s quite small difference, still good enough. :slight_smile: That particular bug is extremely annoying on my Rhino 7, because it literally forces me to lock the viewport before every capture of the viewport, then I have to unlock it again to be able to manipulate the view…

Really a huge difference there on your example :astonished:

Yes, it’s about 30% smaller when the viewport is not locked…
