1530201 - Resizing the browser window is broken with Webrender, Wayland, and Nvidia/EGLStreams

Status: RESOLVED DUPLICATE of bug 1589114

(Core :: Widget: Gtk, defect, P5)

Description

[milos.hadzic]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

I can reproduce this every time on my machine with the following setup:

1. NVIDIA drivers (415) with KMS enabled.
2. Wayland enabled on Gnome Shell (Fedora 29)
3. Firefox Nightly with WebRender enabled

The issue happens when I try to resize the browser window

Actual results:

I resize an outline of the browser but the browser content stays the same visibly (see the attached screen recording). I can force the browser to repaint by moving a tab out in a new window. This does crash the screen recorder so it's not visible in the recording.

It doesn't seem to be a bug in mutter because other windows can be resized. I am not sure though.

Expected results:

The browser window should resize itself as usual.

Bug is still there with the NVIDIA 430 driver.

Does this problem also happen without WebRender/OpenGL?
(gfx.webrender.all;false gfx.webrender.enabled;false layers.acceleration.force-enabled;false)

Hi,

Sorry for the delay in response. I was away from the computer on which I can test. Here are the results

Compositing	Settings	Problem
WebRender	gfx.webrender.all=true	Yes
OpenGL	gfx.webrender.all=false layers.acceleration.force-enabled=true	Yes (although perhaps a bit less severe since typing in the address bar causes a repaint)
Basic	gfx.webrender.all=false layers.acceleration.force-enabled=false	No

Hope that helps, and please let me know if you need any other details.
