Subject: [PATCH] Fix issue with repeated window size changes
Check if the new window size is different from the size requested
previously before calling wl_egl_window_resize. It addresses the issue
where repeated setGeometry calls between two sizes might not work as
expected. The problem occurs when wl_egl_window_get_attached_size does
not get the same size that was requested by the previous setGeometry
call. If the returned size happened to match the new size instead,
we would mistakenly skip the resize.
