VSCode changes position of cursor while typing

[noahweasley]

Issue Type: Bug

When typing in VSCode editor, when I click on the 'Enter' key, to move to the next line, the cursor appears on my preferred editor column and row (according to my default formatter indentation), but it later moves to the far left of that specific row in which I am typing.

For example, when the cursor is on column 10 of row 70, the cursor moves to column 0 of row 70 (assuming the first column of the editor is on column 0). VSCode also seems to move my cursor when I type other characters, as if it were performing 'Format on type' as I type. It interferes with everything I am doing and I sometimes make silly mistakes while typing. I ran Extension Bisect on VSCode and at first, the bug was gone. Extension Bisect finished but didn't fix the problem

@noahweasley Does this issue reproduce in a simple plain text file?

• create a new file file.txt
• type 4 spaces and hello
• press Enter
• does the cursor "jump" to the left?

[noahweasley]

@alexdima It occurs in any kind of file. I tried it on Javascript, C#, HTML and CSS, so am guessing it would still produce the same output

I ran Extension Bisect once more. Immediately it disabled 5 extensions only and the problem disappeared, I immediately uninstalled the 5 extensions. I restarted VSCode and it worked fine. But the question now is Why didn't Extension Bisect work the last time?. VSCode reported that the problem might be from VSCode itself. So I was confused.

Why didn't Extension Bisect work the last time?.

Extension Bisect works every time the same. It picks half the extensions, disables them, then asks you if the problem reproduces or not. If your repro steps are not 100% consistent (i.e. the issue reproduces only 4 out of 5 attempts), then the answers you provide to Extension Bisect are not 100% accurate. Extension Bisect will simply follow your Yes/No answers.
