This is with webkit2gtk3-2.36.0-1.fc36.x86_64 epiphany-42.0-1.fc36.x86_64 but reproduced also with the MiniBrowser, thus filling here. Open: https://finance.yahoo.com/quote/TSLA?p=TSLA You'll be asked for cookies, I simply disable everything, which is two-clicks task here - thank you Yahoo!. Two problems: 1) after the page loads see the graph and keep the page staying; enjoy a WebKitWebProcess chewing your CPU. 2) scroll lower on the page - there's a video; - epiphany has an "autoplay without sound" by default, unless you happen to disable it earlier, once the video loads the page freezes, completely; I tried to Deny autoplay, but it didn't help, the page froze anyway. - Minibrowser - claims missing H.264 (High Profile) decoder. - keep the message there and scroll lower on the screen, until the video is shown and it begins loading; wait several seconds, once CPU calms down the page is frozen. I moved even lower on the page, but I think the problem is once the video loads
Michael, did you remove the "Performance" keyword intentionally? This does relate to performance, a lot.
Yeah, that keyword is best reserved for developers working with performance tests.
This seems to cure with the 2.36.1 update, thus I'm closing this.
(In reply to Milan Crha from comment #3) > This seems to cure with the 2.36.1 update, thus I'm closing this. Oh, I'm sorry, it seems Yahoo! update the page and it's still there. I guess it's related to the videos on the page, though it's killing the CPU even when I have the video autoplay set to "Deny" in the Epiphany.
I can reproduce issue #1 but not #2 with Ephy TP.
