I've noticed an odd bug with the latest version of CoreShell (3.5).
I'm using ZSH, with Oh-My-ZSH installed, with the autocomplete extension. When I start typing a command I've used before, I get an autocomplete popup that I can either ignore or use to auto-complete the command.
When a suggestion pops up, I can't see the cursor anymore. It's clearly still there, but it's an opaque square that covers up the character beneath it. Right now, it's black on a black background when it bugs (instead of green on a black background), which is fairly confusing.
It's been entirely too long since I've coded anything, and I never did a lot of GUI work, but I wonder if this might be an alpha channel issue?
Here's an example.
If I give focus to another application (like this browser window), it's visible again.
