Using transform -> perspective causes lines that were straight to become curved?!?

Trying to do some perspective drawing - using edit->transform->perspective to distort architectural drawings into place. When I do small distortions it seems to work fine, but larger distrortions cause straight diagonal lines to start curving - see attached example:

Is there a way to stop that happening? It makes it way harder to do old-fashioned perspective stuff like this ConceptArt.org: Art Forums, so much of it involves having diagonal construction lines, and obviously if they're curving it's impossible to figure out what on earth is going on!

Thanks!

He did - see his example on the left.

I can reproduce this as well, and in my mind this is a rather ugly bug. I tried the same transformation in other software, and it transforms correctly in those.

I read that he had used Transform Perspective in both cases. The right image had just transformed further.
Perspective Warp does not seem to suffer this issue

yup, that's correct davescm - they're both using "transform perspective", but when you go beyond a certain point it starts curving. I actually do quite a bit of perspective drawing in photoshop, using that tool a lot, and haven't noticed this before - not sure if that's because it only occurs with extreme distortions or because it's a recent bug/"feature" though :-) Thanks for adding the bug, think it probably qualifies as one...
