Description Maciej 2014-08-27 13:31:51 UTC
Created attachment 105337 [details] screenshot of the issue Unity is invisible when using latest mesa git from Oibaf PPA. It started happening after update from yesterday or two days ago (updating almost daily). Ubuntu 14.04 with kernel 3.16.1 and Ubuntu 14.10 with kernel 3.16.0.
Comment 1 Alex Deucher 2014-08-27 13:35:28 UTC
Please attach your xorg log and dmesg ouput. Can you bisect mesa?

Comment 5 Maciej 2014-08-27 14:01:33 UTC
I have no idea how to bisect mesa tbh. I'll look into it later and see if I can manage.

Created attachment 105341 [details] systemd-logind fail Not sure if it's relevant, but this shows up along with latest mesa and those Unity glitches.

I'm using oibaf's ppa with Ubuntu 14.04 and I can confirm that it's happening as the OP reported. (Attaching my Xorg.log to help with the ticket)

I haven't seen this myself yet, but several people have bisected these problems to your commit above. The only obvious semantic difference I can see before and after the patch is that before it, all formats out of a group with at least one unsupported format were converted, whereas after it, supported formats are always used directly, even if some other related formats are not supported.

Created attachment 105365 [details] [review] u_vbuf: Make sure all caps are initialized Does this patch help? I think caps.user_vertex_buffers being randomly 1 could explain the symptoms.
