After commit a9fb331e ("wayland/egl: update surface size on window resize"), the surface size is updated as soon as the resize is done, and `update_buffers()` would resize only if the surface size differs from the attached size. However, in the case of swrast, there is no resize callback and the attached size is updated in `dri2_wl_swrast_commit_backbuffer()` prior to the `swrast_update_buffers()` so the attached size is always up to date when it reaches `swrast_update_buffers()` and the surface is never resized. This can be observed with "totem" using the GDK backend on Wayland (the default) when running on software rendering: $ LIBGL_ALWAYS_SOFTWARE=true CLUTTER_BACKEND=gdk totem Resizing the window would leave the EGL surface size unchanged. To avoid the issue, partially revert the part of commit a9fb331e for `swrast_update_buffers()` and resize on the win size and not the attached size.
