--- Comment #23 from Błażej Szczygieł <[email protected]> --- > The background is a subsurface.

I'm sure it worked a while ago (now doesn't on 6.4.5 and 6.5.1). I noticed FF reports opaque region as 1920x1080 (scaling 200%, WAYLAND_DEBUG=1). These are opaque regions for Firefox (1024x768 logical kwin size): - QRegion(0,0 1024x747) - QRegion(0,0 1024x768) They indeed don't match, that's why kwin tries to check for background color. Could it be a Firefox bug or there's another weird unhandled logic there? --- Question about direct scanout with ICC or Night Light - I can see in code that direct scanout is allowed in this case (color performance mode), but this fails in "prepareAtomicPresentation": "differentPipelines" is set (when I ignore it, no color profile is applied obviously). Is it possible somehow to use DS with ICC/Night Light? -- You are receiving this mail because: You are watching all bug changes.
