User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:147.0) Gecko/20100101 Firefox/147.0

Steps to reproduce:

  1. Setup multi monitor with multi GPU (primary GPU is dGPU)

iGPU: Intel HD Gprahics 4600 (Core i7-4770S)
dGPU: Radeon RX 6700 XT

monitor list:
Display (JPN2500): 1920x1080 in 25", 120 Hz [External] dGPU
Display (FTD-G16AS): 1280x1024 in 16", 75 Hz [External] iGPU
Display (MP156Y2-M): 1920x1080 in 19", 60 Hz [External] iGPU

DE: Sway 1.11 (wlroots 0.19.2-1.1 ChahyOS x86_64-v3 repo)

  1. open Firefox (v147.0b3, Arch Linux)
    open popup (ex: Bitwarden)
    open new private window

Actual results:

The window will only be drawn with the background color.
Components inside the window respond to the mouse.

Expected results:

The window will be drawn as usual.
This problem is resolved for normal new windows if you set "Homepage and new windows" to something other than "Firefox Home" (ex: Blank Page).

If layers.acceleration.disabled=true is set, private windows will be drawn.
However, it is drawn to the full screen size excluding the status bar, and will not be redrawn even if you operate it.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Component: Untriaged → Graphics
Product: Firefox → Core

When using Xwayland by MOZ_ENABLE_WAYLAND=0 (and layers.acceleration.disabled=false),
private windows and popups will be drawn correctly and work.

Both iGPU and dGPU use Mesa driver.

Is this a regression? Can you use mozregression?

OS: Unspecified → Linux
Hardware: Unspecified → Desktop

(I'm currently investigating whether this is a regression or not. Please wait for a while.)

I'm not sure if it's related to this bug,
but changing the title bar settings causes Firefox to freeze,
and on the next startup only the background color is drawn (regardless of the homepage).

This bug may be specific to my profile.
It cannot be reproduced with an empty profile or mozregression.
I would like to add that I am using Profile-sync-daemon.

Adding to Triage so we can follow-up after the holidays.

MetaMask's popup can be drawn.
I don't know why.

Thank you for uploading your about:support. Looks like you have 40 extensions installed. Since this isn't happening for you on a clean profile (no extensions), would you be willing to systematically disable extensions and see if that identifies a particular extension that is causing this problem?

Flags: needinfo?(akkun11.open)

This bug occurs even in safe mode, so I don't think extensions are involved.

Flags: needinfo?(akkun11.open)

Martin, we're not sure what to ask for to diagnose this further -- it goes away with a clean profile, but not with safe mode (which should have much the same effect). Do you have any ideas on how to proceed?

Flags: needinfo?(stransky)

Sure, will handle it.

you have enabled experimental/unssuported yet feature. So this looks like a Sway compositor bug - please file it there.

Summary: New windows, popups, and private windows are drawn only in the background color. → [Sway] New windows, popups, and private windows are drawn only in the background color.

btw. the compositor is used for HDR rendering - Bug 1642854.

You can try the same profile in Gnome/KDE to make sure it's Sway compositor issue.

I have a similar problem with Hyprland.
Sometimes normal windows are not drawn either.

(I updated packages, firefox-developer-editon is now 148.0b9-1.1)

Applying this prefs.js makes Firefox broken.
Creating a new profile and copying this prefs.js broke private window rendering.

These prefs stand out to me

widget.wayland.opaque-region.enabled
privacy.fingerprintingProtection
layout.css.prefers-color-scheme.content-override
layers.gpu-process.enabled
gfx.webrender.compositor
browser.tabs.inTitlebar

try changing the value of these prefs to default and see if that fixes it.

My Firefox Developer Edition is no longer broken. (I don't know why)
Attach my current prefs.js.
