Selecting with the rectangular marquee tool while zoomed always beachballs

[Matthew_Frederick]

If I'm zoomed in quite a bit — like 400–800% — and I use the rectangular marquee tool to select an area, dragging against the edge of the window to scroll and select more than is visible at once, after releasing the mouse the cursor beachballs (Mac) and takes multiple seconds to complete and display marching ants.

I'm sure it's having to calculate the offscreen pixels that will be selected, but the documents are only like 1000x2000px. This happens even if I only have a single layer.

Everything else is plenty fast enough. Any suggestions about what's going on and how to fix it?

Hi Matthew,

May I know which version of Photoshop are you using?

Try unchecking Use Graphics Processor from photoshop's preferences.

I'm running what I believe is the latest version, specifically 20161130.r.29 x64. This has been a problem for many versions, though.

Surprising to me, Use Graphics Processor was already turned off. Should I perhaps try turning it on, instead?

[Matthew_Frederick]

I tried it with Use Graphics Processor turned on and still had the same problem.

Thank you for trying out the steps Matthew, Could you provide some more details about your system specifications?
