Layer surfaces are not notified of cursor position changes if the surface moves, only if the cursor moves. This workaround emits a cursor position event every time a cursor ends up over a newly resized layer surface to make sure the following clicks land in the right place.
This change doesn't address sending leave events when a cursor previously present over the surface becomes away.
There are 2 separate mechanisms in play, because a layer surface gets resized in 2 steps:
1. Layer surface resize & rearrange.
2. Underlying surface resize.
The first step may affect all layer surfaces. The cursor events are sent to cursors placed over all layer surfaces which have moved (not been resized). The second step affects any layer surface whose surface changed size. The cursor event is sent only to that surface.
Together, these events cover all surfaces: those which moves, and those which changed size, as long as each layer surface resize is accompanied by an immediate surface resize.
After destroying a keyboard input device, seat's listeners could still be pointing to destroyed wlr_input_device signals. This patch makes sure the references are removed while the input device is being destroyed.
On some systems (most notably laptops with two GPUs) there are GPUs that
don't have attached outputs. However, we still want to load those GPUs
because they could still be used by the compositor for rendering.
All screens on secondary GPU in multiple GPU configurations
was flipped 180.
The flipped screens was always on secondary card (the primary card
was always correct).
Tested on nouveau with:
WLR_DRM_DEVICES=/dev/dri/card1:/dev/dri/card2
WLR_DRM_DEVICES=/dev/dri/card2:/dev/dri/card1
The commit is fixing this problem. Now all screens are "normal".
backend_get_renderer() is now returning the renderer of the primary GPU, instead
of its own renderer, since that's the thing which actually does all of the "real"
rendering
wlr_multi_backend_add() is now adding all subbackends (otherwise only one GPU
is handled).
