All software that’s popular has hundreds or thousands of issues filed against it. It’s not an objective indication of anything other than people having issues to report and a willingness and ability to report the issue.
It doesn’t mean every issue is valid, that it contains a suggestion that can be implemented, that it can be addressed immediately, etc. The issue list might not be curated, either, resulting in a garbage heap.
For what one anecdote is worth: through casual use I've found a handful of annoying UI bugs in Claude Code, and all of them were already reported on the bug tracker and either still open, or auto-closed without a real resolution.
