2012301 - [Linux/Plasma/Wayland] Turning on HDR and then scrolling in a specific way causes window to freeze

Status: UNCONFIRMED

(Core :: Widget: Gtk, defect, P3)

Description

[Erista Tessie]

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

Steps to reproduce:

Starting from a clean profile:

1. Turn on gfx.wayland.hdr and gfx.wayland.hdr.force-enabled in aboutsaw:config, restart the browser so that these changes are applied
2. Open https://rtypetactics.com, wait for it to load (not the only page where I had this happen, but it works for reproduction)
3. Using a touchpad, overscroll upwards a little and then scroll downwards; repeat a few times if the issue does not trigger at first

Actual results:

Rendering completely stops for the entire Firefox window; sometimes a crash happens.

Expected results:

No hangs happen; browser continues to function normally.

(kde) wp_viewporter#35: error 0: the specified surface already has a viewport
Proxy: WP:E WP:CA WP:CPCA

That's interesting, Thanks.

Can you please run on terminal with WAYLAND_DEBUG=1 MOZ_LOG="WidgetWayland:5" env variables and attach the log here?

Log from inducing a hang with WAYLAND_DEBUG=1 MOZ_LOG="WidgetWayland:5" set. No crash as I'm unable to cause these reliably.

I recently turned on HDR on Firefox 147 on Linux using the gfx.wayland.hdr flag and started experiencing this an issue where typically after scrolling the current Firefox window would freeze for awhile. I'm also using Plasma and Wayland. I found this bug report after a few days of experiencing it and turned the flag back off, which has fixed the issue, so I assume it's the same/a related problem.

Same issue here on Gnome with gfx.wayland.hdr.

[Martin Stránský [:stransky] (ni? me)]

Yes, I can reproduce that on Gnome too.

I experience the same thing on KDE Plasma 6.5.5, after diabling gfx.wayland.hdr, everything turns normal.

I can confirm this bug as well on CachyOS running KDE Plasma 6.6.2
GPU: RX 7900XT
Mesa: 26.0.1

I often click on a new tab (nothing happens), minimize firefox, then open it again and it unfreezes.
