Hello! Hm. Could you see if #553 (branch fix/ui-augroup-del) fixes this?

[alexmaloteaux]

still the same , however it seems that just , launching nvim , then Mason and quitting it (with escape), doesn't immediately trigger the error message. A minimum of "activity" is necessary, otherwise the error msg is not triggered.

Sorry for the poor description but i didnt found a pattern to have it 100% persistent :) br

[williamboman]

Which steps (from start to error) do you do to trigger this error?

[alexmaloteaux]

launch Mason with :Mason optionally do some activity like install/update/browse then quit with ESC

the issue start randomly from first up to 10+ launch, from there appears "almost" permanently on each subsequent launch

I'm going to close this as there have not been any other reports regarding this, and I've been unable to reproduce.

I experience the same problem, except the error is now in line 506. I can reproduce it with double-hitting the ESC key, therefore I guess the buffer is already being removed but the keybinding is still active and fires without being able to remove it. Do we know why pressing Esc is so much slower than q?

I found this (https://www.johnhawthorn.com/2012/09/vi-escape-delays/) and noticed that my delay was caused by tmux. While the error still exists, now we avoid running into it.
