Discussion:
Verified twice and bisected to this range: Steps to Reproduce: some repo a change the diff view and set the cursor like this: <img width="1273" alt="Screenshot 2023-06-20 at 17 18 51" src=""<kbdCtrl</kbd+ <kbdC</kbdto the right side, put the cursor between text e.g. line 32. <kbdCtrl</kbd+ <kbdV</kbdExpected: The new line should be placed above <img width="683" alt="image" src=""Actual: The line line breaks and modifies cursor line + line below <img width="709" alt="image" src=""
Is this just the diff editor or does it happen in every editor?
I feel like the "line copy" from the left side in the diff editor is busted, when I then use this clipboard to paste it on the right side of the diff editor, or a normal editor it ends up in the unexpected state. Doing a "line copy" from a normal document, and pasting it into a normal editor or right side of the diff editor is still fine.
Unfortunately, I cannot reproduce. ! Pasting just triggers indentation.

Let me know if you need something else. My list of extension is the following and hasn't changed over the last year, and I think using the bisect-vscode script it disables all of them since its a new profile. <table style="box-sizing: border-box; width: 575px; max-width: 100%; background-color: transparent; border-collapse: collapse;"<tr style="box-sizing: border-box;"<th style="box-sizing: border-box; vertical-align: bottom; border-bottom: 1px solid; text-align: inherit; padding: 5px;"Extension</th<th style="box-sizing: border-box; vertical-align: bottom; border-bottom: 1px solid; text-align: inherit; padding: 5px;

Do you have any settings that could cause this?
bisect-vscode uses a new profile, so all the settings were default settings. I can try to bisect it down from the range to the individual commit if you want, 45 commits should be ok.
That would be awesome!
Bisected to and turns out if you set which is by default it behaves how it was before. cc
