Thanks!

Unfortunately it didn't, X still crashes.

Attached is backtrace with it. Mesa still gets format=ISL_FORMAT_UNSUPPORTED.

Were you able to verify that you got modifier support for onscreen buffers?

Note: I haven't tested this with X server v1.20 release, only with git versions
of X server.  However, I've tested X git versions both from before 1.20 (when X
had everything required for modifiers) and after it, with the latest Mesa and
there's crash with both.

Currently I'm using:
