Screenshot with DMA-BUF enabled for WebGL
Reproduction on latest nightly:
- Force-enable OpenGL compositing.
- Enable
widget.wayland_dmabuf_webgl.enabled - Run WebGL aquarium test (https://webglsamples.org/aquarium/aquarium.html)
Tested on intel integrated graphics with sway/wlroots.
Observed result
Increased performance, but with swapped color channels (red/blue swap).
Expected result
Increased performance with same output.

That's very interesting, Thanks. It's because I tested that on https://webglsamples.org/blob/blob.html where the colors are not so visible :)

I can reproduce this with OpenGL layers, but not basic layers or WebRender.

I expect it may be also broken in gl compositor when "widget.wayland_dmabuf_textures.enabled" is set to true.
