I installed the new version and 0.13.2 doesn't manifest this problem. Thanks!

Are you suggesting that fstat itself is causing the used file descriptors to increase? Also have you tried a different shell?

fstat seems irrelevant. ls -l seems to be a good way to trigger an fd opening spree.
I just tried /bin/ksh and /usr/local/bin/bash which produce different behaviors compared to my default zsh. I'm still confused though. How can the choice of shell affect the FDs opened by the alacritty process?

Here's a longer fragment of ktrace which hopefully can help identify the code where this activity originates. It doesn't make much sense as the files get open and then ignored:

I'm still confused though. How can the choice of shell affect the FDs opened by the alacritty process?
Alacritty is responsible for spawning the shell, so the shell is going to be its child. I know that strace requires passing -f for inspecting children but maybe ktrace does so by default?
So far it doesn't actually look like an Alacritty issue, if you have any questions or other details feel free to ask.
