Weird rendering issue by changed color scheme (after upgrading to debian 12)

[fhoshino]

Using zsh, try to list files with ls, got some files listing as empty string,

While using bash those files showup without a problem,

Using alacritty doesn't yield this problem, and this problem exsit only after upgrading to debian 12 using wsltty, ssh back to a debian 11 box the problem disappeared.

Please provide a screen log, e.g. using
ls | tee log

Pasting it here filters out the control characters. Please upload the file log.

ls will normally not use color mode if STDOUT is not a termainal.

We might need ls --color=always | tee log.log

[mintty]

Yes, please repeat the test case and upload again.

\e[00;90m This seems to be Bright Black foreground. Which I bet is #000000 the same as your black background… 😬

Maybe in the most common terminals for debian they have a different color for bright black? One with crappy contrast, but at least visible. Meanwhile, for us, it shows up as just black? I’m curious why it has 00, as that’s technically not valid? If it’s for “All attributes off” it should be 0, the same as just before the end of the line…

You might want to consult with dircolors to see if there’s an entry that matches, and set it to a different color. (This is just a pointer to what you could look at, I’ve not edited any dircolors in like 20 years, so I regret that I cannot help further.)

Oh god, you saved me, tinkering with the color scheme I am able to see the file name again.
