@leocg - Thanks. It says #disable-accelerated-2d-canvas underneath 'Accelerated 2D Canvas', but the option on the right of it is 'Enabled' already. So I don't know what that means, it sounds like a contradiction but I have no idea about this stuff.

and this isn't just a problem with Tradingview. You can see and feel it on the Bitcoin charts at bitcoinwisdom.com – they never lagged like this before the update in Opera & Chrome

Hi @ezodi, what happened is that Chromium put your combination of GPU (Intel) and OS (macOS 10.11?) on a blacklist because it was causing rendering corruption issues. You can read more details about that issue on https://bugs.chromium.org/p/chromium/issues/detail?id=794819. To fix the rendering corruption, they have disabled acceleration of canvas / rasterization.
I recommend you keep all your settings on default, there's really not much to do here. The only real way to fix it is to update macOS to 10.12 or higher (the bug in the GPU driver that causes the rendering corruption was seen only in macOS 10.10 and 10.11, which is why they only disabled acceleration on those systems).

Hi @avl – first of all thank you very much for all the work you've put in to figure this out. I'm grateful for your help.
Maybe it's superstition, but I had noticed my 2013 Macbook Air was slowing down a bit and I didn't want to upgrade to Sierra in case it exacerbated that. I've done it now though – 10.13.4 – and like you said it's fixed the problems with Tradingview, both for Opera and Chrome. It's fast and smooth again, more so in Opera than Chrome I think.
I find it a bit strange that the acceleration was disabled when I never experienced a problem with anything until the new upgrade, but that's all done now. Opera's great and I'll continue to use it as my main browser.
Thanks again for all your help. Cheers.

Yes, unfortunately sometimes there's a tendency to blacklist more rather than less, since it's hard to tests all exact combinations of GPUs and OSes and in general it's better to be on the careful side (better a slow browser than one that doesn't work is the thinking). So it's perfectly possible that your exact GPU/macOS version didn't show the symptoms and was blacklisted unnecessarily.
