--- Comment #37 from Michel Dänzer <[email protected]> ---
I was able to reproduce the problem. It's a modesetting driver bug, this code
in ms_dirty_update:
msPixmapPrivPtr ppriv =
msGetPixmapPriv(&ms->drmmode, ent->slave_dst);
probably needs to be:
msPixmapPrivPtr ppriv =
msGetPixmapPriv(&ms->drmmode, ent->slave_dst->master_pixmap);
otherwise it tries to access random memory when the slave screen doesn't use
the modesetting driver.
There might be more related issues.
