@smlombardi Those spaces get added when pressing enter and they are not "garbage-collected" when pasting, my guess because they are near to the range (touching) where the paste occurs. This becomes a lot more clear if you enable renderWhitespace:

We need to investigate why the auto-whitespace is not removed in this case, my guess is that the paste edit range touches the auto-whitespace, tricking it into thinking it was useful, when in fact it wasn't.

As a workaround, if you copy without a selection, pasting will always paste a new line above your cursor position. I use alt+up/down to adjust if it wasn't perfect.

Thanks for the tip. I don't recall this happening in older versions.

Maybe you had enabled trimTrailingWhitespace in the past and/or auto-save ... ? But this behaviour is in since ... forever :)
