This is imported given how
https://github.com/pop-os/cosmic-protocols/pull/39 uses this event.
But the protocol spec also states the event "is emitted on creation" so
this is seemingly incorrect regardless.
This should fix an issue where output hotplug can sometimes cause
clients (including XWayland) to crash with a protocol error trying to
bind the output.
Using a timer doesn't seem ideal, but seems to be the correct way to do
this at present. Wlroots `wlr_global_destroy_safe` is basically the same
as this.
Adding a `LoopHandle` argument to `OutputConfigurationState::new` seems
awkward, but maybe better than a handler method for removing globals.
(`IdleNotifierState::new` also takes a `LoopHandle`). Perhaps Smithay
could provide some kind of helper for this.
Having if conditions for these is unnecessary when they should never be
reached. (This is commonly unwrapped in `smithay`.)
Some of these else conditions fail to call `data_init.init` with a new
id, so they'd result in a crash later anyway.
This meant that, for windows that were not fully opaque, there was no
way to capture their transparency. No way to put a window with
transparency on top of a background in OBS, for example.
`Output` in Smithay doesn't track if the output still exists, other than
based on whether or not it has strong references. Which doesn't seem to
be working correctly.
There may be leaked strong references to `Output`s somewhere, and maybe
Smithay should track if an output is still valid, generally when it is
exposed as a Wayland global
(https://github.com/Smithay/smithay/issues/1584). But a check like this
works for now.
Addresses https://github.com/pop-os/cosmic-comp/issues/985.
`from_raw_parts()` is only sound if the alignment is the same, so it
can't be used to covert to a `Vec<u8>` from a type with a greater
alignment.
This isn't hard to avoid, luckily.
It seems we allocate a new `GlesRenderbuffer` every time we screencopy
to an shm buffer.
We probably should use a more complicated approach to do proper damage
tracking without any unnecessary copies, and re-using the GPU buffer,
but as long as this allocates a buffer the age of that buffer should be
treated as `0`.
Fixes corruption in cosmic-workspaces when shm screencopy is used. (For
instance, when Cosmic is run with software rendering.)
