--- Comment #10 from Clemens Eisserer <linuxhippy at gmail.com> ---
I bisected the regression again, this time with the benchmark mentioned in the
post above (JXRenderMark) and I was agin led to the following commit:

[ce at localhost mesa]$ git bisect good
8b3a257851905ff444d981e52938cbf2b36ba830 is the first bad commit
commit 8b3a257851905ff444d981e52938cbf2b36ba830

    radeonsi: set a per-buffer flag that disables inter-process sharing (v4)


So regardless of different manifestations, this commit seems to introduce
regressions for antialiased rendering using the Xrender Java2D backend.
