What sorts of issues? For me, performance is the issue, I've never found JIRA buggy or inadequate, and I'm generally able to find a given ticket and interact with it in the expected way.
I'm not sure how you can have used the UI and hold this option. I feel like I've been greeted by the same basic bugs time and time again, like clicking on an issue ans it not opening until the second click, or opening the previously viewed issue.
