1610716 - [wayland] WebRender + dark theme leaves artifacts after resizing

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

[Emilio Cobos Álvarez (:emilio)]

On a clean profile, wayland enabled:

• Enable WebRender.
• Go to customize mode, set dark theme.
• Restart.
• Move window all the way to the right or left (though probably any other resizing works too).
• Unpin it, moving it around

ER:

• Window moves, like WR-disabled / WR-enabled-light-theme

AR:

• Window leaves tearing artifacts behind. Also, the window corners are no longer rounded, which I think is related.

I think the corner thing is somewhat expected (happens also without WR). But it's probably related.

It also seems like the kind of thing which may be a compositor issue, as I'd expect the stuff outside the window to not be managed necessarily by Firefox...

I think this has been fixed by now, especially after bug 1617002 landed - Emilio, can you confirm?

Yeah, haven't seen this in a long while.
