We cant make window visible after createwindow has returned because we
want to loop till the compositor fully creates the window and that loop
requires attaching a single pixel buffer to the window surface which
cannot be done once an OpenGL context is created for the window.
As far as I can see the preshow callback is not used on Wayland for
anything, so this should be OK to do.
Apparently with explicit sync it is now not possible to attach a
temporary buffer to a surface that also has an OpenGL context. So we
first attach the temporary buffer, and only after we are done waiting
for window creation do we attach the OpenGL context to the window
surface.
Fixes#7767 (maybe, not installing sway-git to check)
labwc is unique among Wayland compositors in implementing fractional
scale but not preferred integer buffer scale events. We didn't cater to
this particular combination of before. And to top it off it appears to
have no way for the user to set/control the scale so I cant even test
what it will do with fractional scales other than 1. Sigh. As with all
things Wayland, you need to be a masochist to subject yourself to them.
Fixes#7540
Apparently NVIDIA drivers dont handle this well. Sigh.
Go back to calling wl_egl_window_resize() before resizing the
framebuffer instead of before swapping in the resized framebuffer.
Logically, these should be equivalent, but...
Wayland is such an ongoing disaster.
Fixes#7493 (I hope).
Call wl_egl_window_resize just buffer swapping buffers at which point
the context is already correct.
Also might workaround bugs in the NVIDIA driver: https://github.com/NVIDIA/egl-wayland/issues/52
When showing the window we loop in the wayland backend using a
temporary buffer of blank pixels to force the compositor to finish
setting up the top level surface pronto.
TODO: Set the color of the temmporary buffer to the background color
Avoids a bunch of SIGIWNCH during child startup as not all programs
handle these correctly. Sadly adds about 0.1 seconds of latency to
startup. Will have to look into reducing that. The Wayland protocol is
*so badly* designed.
