2035958 - Firefox linear-gradient artifacts on Firefox 150

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect)

Description

[bwhvibz0c]

Attachment: image.png

Steps to reproduce:

1. nix run github:NixOS/nixpkgs/1c3fe55ad329cbcb28471bb30f05c9827f724c76#firefox -- --profile $(mktemp -d)
2. open https://claude.ai/downloads (login required, I can't make a simple reproduce)

Actual results:

Firefox shows large rectangular rendering artifacts in a web page UI when running on NixOS unstable with Hyprland. The issue is visible on the physical display and is captured by grim, but Firefox’s internal screenshot tool captures the page correctly.

Expected results:

No artifacts with nix run github:NixOS/nixpkgs/c5f45036e6653f9855f5b05f2a43e05ea072fde2#firefox -- --profile $(mktemp -d) (Firefox 149)
