I do not think this is a duplicate of bug #1745799.
At this comment I will try to give a code to solve this bug.
My symbol Xwaylnd-crash shows the next trace:

Problem can be solved by using slicing at shm_buffer_attach() at
src/wayland/meta-wayland-buffer.c, if size of texture is too large for
graphics card. Code for freeing the bitmap is now positioned after the
if.
This results into the following code:
texture = COGL_TEXTURE (cogl_texture_2d_new_from_bitmap (bitmap));
cogl_texture_set_components (COGL_TEXTURE (texture), components);
if (!cogl_texture_allocate (COGL_TEXTURE (texture), error))
{
g_clear_pointer (&texture, cogl_object_unref);
texture = COGL_TEXTURE (cogl_texture_2d_sliced_new_from_bitmap (bitmap,
COGL_TEXTURE_MAX_WASTE));
cogl_texture_set_components (COGL_TEXTURE (texture), components);
if (!cogl_texture_allocate (COGL_TEXTURE (texture), error))
g_clear_pointer (&texture, cogl_object_unref);
}
wl_shm_buffer_end_access (shm_buffer);
cogl_object_unref (bitmap);
buffer->texture = texture;
This code is working and makes it possible to login with wayland with
dual screen without any monitors.xml-config on small/old graphic cards.
Slicing is causing next message:
Oct 13 15:51:36 Gert2 gnome-shell[1994]: Skipping layers 1..n of your pipeline
since the first layer is sliced. We don't currently support any multi-texturing
with sliced textures but assume layer 0 is the most important to keep
