A newbie task: [Bug 78585] multiple monitor fullscreen images incorrect position/scale

[Pekka Paalanen]

Hi all,

there have recently been many questions about where to start learning or
hacking Wayland. Here is one suggestion.

The bug referred below is about some misbehaviour with fullscreening an
SDL2 game under Weston. If you want to dive into Wayland and Weston,
you could:
- try to reproduce the original problem, or
- try to hack simple-egl to reproduce the problem, as suggested below
- bisect Weston to find out when it broke, or if it was broken to begin
  with
- attempt to fix it in Weston


Thanks,
pq

Ryan, would it be possible for you to try Weston 1.4.0?
That would tell if this is a regression. If it is a regression,
bisecting could help get developer interest.

Also, I think one might be able to reproduce the problem by hacking
weston-simple-egl from Weston 1.4.0 (when it was still using wl_shell
interface) to reproduce the circumstances that trigger the problems.
(This would be a perfect task for anyone wanting to become a Wayland
developer, btw!)

wl_shell, which SDL2 uses for the time being, is being replaced by
xdg_shell, so it is possible something broke in wl_shell if it wasn't
broken to begin with. Unfortunately it also means that wl_shell is not
too interesting.
