Damage is not handled properly when subsurfaces have subsurfaces. Of course firefox is doing this because, why not. Anyway, those need to know their parent as well to figure out the right location for the damage.

Initialize the current workspace with the noop workspace right away, that way we can prevent hitting a NULL pointer when typing during startup.

Subsurfaces are handled differently in wlroots 0.14.0. We now need to interate over all the subsurfaces above and below the parent.

This has been removed from wlroots 0.14.0.

The WL constants yields an unsupported format after switching to wlroots 0.13.0.

The WL constants yields an unsupported format after switching to wlroots 0.13.0.

This is not always the case so we better check.

We should not need to clean up the noop display explicitly anymore.

This uses the DRM constants for background loading. Otherwise backgrounds will fail to load on newer versions of wlroots.

The code for apply effective surface damage has been duplicated in several places.

Subsurfaces have been handled somewhat incorrectly. With the release of Firefox 87 this happens to trigger a couple of rendering bugs. Damage is not tracked properly for those subsurfaces.

Clarify hikari-unlocker needs setuid, that hikari does not, mechanisms used to gain root privileges and optional setuid procedure if needed.

There is an issue with sending a resize event to surfaces which would not require them to actually resize. In that case the serial of these operations would be 0. This way the commit logic would not recognize a surface update and handle it wrongly.

This can be reproduced when trying to fullscreen a surface that already has its maximum size.

seatd and similar mechanisms are present on all relevant platforms.

Submitted by: Aisha It's now possible to configure which pkg-config binary should be used.

Pointer devices should be able to configure flat, adaptive and none as acceleration profiles.
