P: Character leading broken

Since updating Photoshop CC, when editing text so that the line spacing is set to a custom size rather than select a predefined value i the 'Character' panel, it jumps to a huge number and errors.  I have tried multiple ways to set is manually but the only way I can get it to "work" is from selecting one of the drop down options which doesn't work for me.

Hi Hans,

This bug specifically deals with transformed text; we've figured out the cause and are working on a solution.  If you're encountering this problem with an existing file, then it was previously transformed.  You won't see it if you create text from scratch without a transformation.  Please try it and see for yourself.

Thanks,
David

We are actively working on a solution.  That said, transforming the text is NOT the same thing as changing it's point size.  Photoshop tries very hard to make it seem so, but under the hood, there's all sorts of math going on to make it work -- if you transform Myriad Pro 12pt by x450%, you've blown up the 12pt type by a 4.5:1 scale; it's NOT the same as Myriad Pro 54pt, though for many fonts it's hard to tell the difference.

It appears that at the 11th hour before shipping, a control that impacted that math was changed, triggering this problem.  So a TEMPORARY workaround would be to simply avoid transforming type until we can get a fix out.

Thanks,
David

Same here on Windows 7, even if the text wasn't transformed before

You can go to Creative Cloud and click "Previous Version" to install 2017.

Same here  @17290952.
And the editing of transformed text (i that means f. e. scaled ) worked without issues in former Versions, so the answer is a bit unsatisfactory.

thanks! used Alt on mac and its fine.

i'm facing the same problem. made me come here for answers.

This version of Photoshop feels almost completely unusable, a 250kb .PSD zooms in and out at a snails pace on a MBPR 2016. Reverting back to 2017 unfortunately. 

I am re-installing CC2017 for now. New update keeps slowing me down with work.
