1496726 - Page content disappears while devtools toolbox is open

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect, P1)

Description

[Josh Matthews [:jdm]]

When I open the devtools, the page content turns white. When I close the toolbox, the page content reappears. This has happened since at least the 9/22 nightly build for me.

I'll see if I can narrow down the window in which this started happening.

I can reproduce this when I zoom the developer tools on Mac.

Hey Andrew, mozregression seems to point to Bug 1485420 as the culprit, and we just made this a P1 bug.  Can you take a look at this as a top priority?  Thanks.

Reviewing the code, I think I should have put the zoom display item on the exclusion list for applying the clip transformation. I'll verify this and double check for anything else I might have missed...
