@ezodi said in New Opera update makes Tradingview charts very slow:
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.
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.
