Cursor briefly jumps to the start of the line (Windows only) #789

Open HernandoR opened 3 years ago

Cursor sways with this plugin,

I currently using MSYS2 in windows 10 with oh-my-zsh.

However, the Cursor will automatically change to the head of the line and then run back where it should be every time I tap the first few letters.

Such thing only happens with this plugin opened, and when I using windows terminal, If I use MSYS2 directly, it does not occur or I haven't noticed.

Seems like it's related to ConPTY winpty/mintty are not affected I faced same issue in any terminal with conpty backend (WIndows terminal/Alacritty/VS Code terminal)

wight554 commented 3 years ago

There's related issue in conpty itself https://github.com/microsoft/terminal/issues/364 But seems like it's dead

@wight554 Thanks!

@HernandoR Does the referenced issue describe your setup too?

If so, we should probably close this ticket as an upstream bug?

wight554 commented 3 years ago

Uh that's an actual nightmare MS guys lost that ticket perhaps, it's been 2 years since the last update If nothing can be don't from plugin side, then there's no choice other than closing ticket

zsh-syntax-highlighting doesn't do anything related to positioning the cursor. zle (part of zsh) might, so you might try asking zsh-users@ with a minimal reproducer (one that's written in zsh -f and doesn't source anything).

Well it happens only with this (or fsyh) plugin enabled Issue I linked higher has repro steps

I've seen that, but I stand by my recommendation to come up with a minimal reproducer, as outlined above — or, at least, as minimal as practicable.

I'm having this same issue, but I thought I would contribute with gif demonstrations, since this problem is kind of hard to describe.

Mintty: with z-s-h, no z-s-h WinTerm: with z-s-h, no z-s-h

I can confirm that the WinTerm behavior is identical in VS Code's integrated terminal.

This is an extremely niche use case (how many people are using zsh-syntax-highlighting on Windows?), so it's probably not a very high priority, and it's just barely noticeable enough to be distracting, but I thought I'd try to document the behavior, in case that's at all helpful.

Version Information z-s-h: 0.8.0-alpha2-dev zsh: 5.8 (x86_64-pc-cygwin) Cygwin: 3.3.4 WinTerm: 1.11.3471.0 Mintty: 3.6.0 VS Code: 1.66.0

@chrstophr-wltrs Thanks, that's very helpful. Could you upload the gifs as attachments to your next comment, please? See instructions at the bottom of the textarea comments are entered in.

Yes, absolutely! Sorry about that, I've updated the links in my first post to point to images hosted on Github instead of gfycat.
