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

Status: UNCONFIRMED

(Core :: Widget: Gtk, defect)

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.
