(Core :: Graphics: WebRender, defect)

Description

[Sotaro Ikeda [:sotaro]]

This bug is similar to Bug 1700101 . I confirmed by using latest nightly with pref gfx.webrender.software.unaccelerated-widget.allow.

STR
-[1] Enable Library icon on toolbar from "customize toolbar".
-[2] Set pref gfx.webrender.software.unaccelerated-widget.allow=true;
-[3] Restart Firefox
-[4] Click on the Library icon from the toolbar.
-[5] Click on the Bookmarks option.
-[6] Rapidly close the panel via "<" button from the sub panel.

Repeat steps [5] and [6], if the issue is not reproduced instantly.

Library icon from the toolbar.

I wonder if a cause of the problem might be similar to Bug 1704431.

Bug 1703741 looks very similar. Then WebRender might not related to the bug.

Are there any errors reported in the browser console when this happens?
