<pre>I can't reproduce it either; actually, I don't see RGBX configs in glxinfo
output, should they manifest there?
Anyhow, can the check in do_blit_drawpixels be relaxed to allow RGBX<->RGBA
blits? intel_miptree_blit is able to handle it per this comment:

About using Meta for Drawpixels, it needs work to avoid regressing performance,
please see discussion in comments 2, 3, 4 at
