Very janky webpage rendering when resizing window from left |
|||||||||
Issue descriptionChrome Version: Stable and Latest Canary (Version 59.0.3051.3) OS: macOS 10.12.3 What steps will reproduce the problem? (1) Visit wikipedia.org (2) Resize the window by dragging the left edge. What is the expected result? I expect the webpage to resize as smoothly as when I resize the window by dragging the right edge. What happens instead? Lots of jumping around of webpage. It's pretty bad. Doesn't occur in Firefox or Safari.

Tentatively tagged this as a Blink>Compositing (?) issue - it seems to only happen on wikipedia.org, to everything above their div.footer element. Interestingly, the jankiness seems to be fixed once I open DevTools and pop it out. I only tested Linux and Mac, but assuming it happens on all desktop because it's Blink.

For me it happens on pretty much all pages, including the NTP (see attachment).

I'm also seeing much worse performance when resizing from the left edge rather than the right, but it's impossible to tell if that's a page content issue. All I can think of is that the window position and size are both changing when you drag the left, whereas only the window size changes when you drag the right. Maybe someone on the GPU side can shed light on why this is happening, or know who to send the bug to next.

Yeah, I think this is likely something that would need to be addressed in compositing.

This is issue 617824 -- this regressed with the update to the CoreAnimation renderer. |
