I've had this happen before seemingly randomly. It may be related to when I zoom in and out in Windows Terminal. I usually have to clear/cls the screen or use CTRL + l to "clear" the screen. I think we'll need a better repro to really get to the bottom of it.

Also see my bug report on oh-my-posh:

JanDeDobbeleer/oh-my-posh#4122

It seems like it is the same. It's easy to reproduce the way I do it, I feel.

Just bumping this - this is quite a weird bug. sim590's bug report is more thorough and reaffirms that this is likely due to PSFzf's implementation and not something about oh-my-posh specifically.

I can't recreate this issue. See the attached video. Do you have a language set other than English?

My environment:

PowerShell 7.4
fzf 0.46.1
Oh My Posh 19.11.3
CaskaydiaCove Nerd Font

No, I use
Shell: PowerShell 7.5.0-preview.2
Terminal: alacritty 0.14.0-dev
oh-my-posh: 19.24.2
fzf: 0.50.0 (f97d275)
PSFzf: c604e1b
Theme: Pure

I ever so slightly modify the Pure theme (I disable the transient_prompt). Repeatedly pressing CTRL+R or TAB can often repro this bug (and make sure you have long shell history, larger than your window size).

@kelleyma49 In your video you seem to mostly be using ENTER or any other key input that would end up selecting the line your cursor was on. However, my report stated that I interrupt the program in order to get the issue, so you would need to interrupt FZF with CTRL+c. Do it repeatedly and you should trigger the issue quickly...

Yes, I typically used ESC

I'm facing the same problem with oh-my-posh and PSFzf.

I can reproduce this rather easily:

My best guess the issue has to do with the fzf preview. If the preview isn't fully loaded, then it'll cause the weird behavior.

Yes, at this point I think I can confirm this.

It seems to be related to fetching the git status in helpers\PsFzfTabExpansion-Preview.ps1.

I can reliably break the output when hitting [Ctrl]+[C] after the Get-ChildItem is executed, but before git log is done in this code-path:

But once I remove the code to fetch git information like this:

I can no longer reproduce the issue
