I've had to download and start using Chrome for Lush because my preferred browser, Opera, has had issues with the recent forum upgrades and fixes and so on. Even after clearing the browser history, content doesn't always render properly (like there are no edit / quote buttons in the forum posts - stuff like that).
Is this a known problem? Being worked on?
Hmm. I haven't used Opera in quite a while, though i knew they were still a going concern. To be honest, it wouldn't surprise me if testing in Opera got overlooked. At work we test in IE, Chrome, Firefox and, going forward, Edge. Those are quite simply the ones that the lion's share of visitors are going to be using. Hope gav and Nic are able to look into your issues.

Since about 5 years Opera and Chrome share their rendering engine (Blink) that's responsible for rendering page layouts on screen. So most stuff that works well on one should work on the other as well. The main difference is in the browsers' interfaces and features that are not directly related to the rendering of the page.
