[Bug 88561] [radeonsi][regression, bisected] Depth test/buffer issues in Portal

https://bugs.freedesktop.org/show_bug.cgi?id=88561

--- Comment #3 from Daniel Scharrer daniel@constexpr.org --- Created attachment 113176 --> https://bugs.freedesktop.org/attachment.cgi?id=113176&action=edit Vertex issues in TF2

I've re-tested Portal with updated mesa (commit 2335153ff2fae01d6294876a86d3eab59c6c4236) and kernel (3.18.5-gentoo) and the issue is still there.

There also seems to be a rendering regression with TF2 for me, but it looks different. Where in Portal objects appear in front of others that they should be behind of, in TF 2 they disappear entirely or appear to have garbage vertices. I haven't yet tested that the TF2 issues were introduced in the same commit.

I'll create apitraces of both later today.
