1403297 - WebRender: Google Docs' hyperlink popup window's "Searching" progress spinner looks like a wheel with spokes

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect)

Description

[Chris Peterson [:cpeterson]]

I enabled WebRender on Nightly 58 and Windows 10 using the instructions in this blog post:

https://mozillagfx.wordpress.com/2017/09/25/webrender-newsletter-5/

STR:
1. Open a Google Doc.
2. Select some doc text and press Ctrl+K keyboard shortcut to create a hyperlink.
3. In the link popup window, start typing in the "Paste a link, or search" text field.

RESULT:
As you type, the rotating image to the left of the popup's "Searching..." menu item has visual artifacts that make the spinning arrow look like a wheel with spokes.

Disabling WebRender and restarting Firefox made the problem go away.

This bug might be related to bug 1401665.

bug 1401665 (currently) does only happen when "webrendest" is enabled on top of webrender etc.
Can you make this problem go away by only disabling webrendest? (A restart is only needed for webrender, but not for webrendest.)

It might also be related to bug 1398092, which I think is not related to webrendest.

I can still reproduce this bug with webrendest disabled.

WFM. There were multiple issues, but the last one was bug 1404158, which got fixed by bug 1413178.
