Thanks for reporting the issue. FYI, it works on my hsw-gt2. @timo, is this just gen4? Could you try something else pre-sandybridge? so far just gen4, and I don't have ironlake :/ verified that sandybridge is fine (In reply to Timo Aaltonen from comment #4) > verified that sandybridge is fine Was mostly curious if it's something old without LLC (or new without LLC) baytrail is fine as well Note that Gen4-5 don't expose GLSL 1.30, so many of Glamor's integer code paths will be disabled (as GLSL 1.10-1.20 allow integers to be represented as floats, so e.g. bitfield tricks may not work). Gen4-5 of course use real integers, so we really ought to find a way to get Glamor using integer paths properly. I believe those paths are faster, as well as better tested. Ian has a couple of GL_MESA_* extensions in progress we might be able to leverage... (I don't know that this is actually the problem, it's just a difference between Gen4-5 and Gen6+ that could be relevant. We'll have to look into it properly.) Tried to reproduce under Xephyr -glamor with server master and Mesa master with MESA_GLSL_VERSION_OVERRIDE=120 MESA_GL_VERSION_OVERRIDE=2.1 on skl, didn't see anything wrong in the default window. I'm on Ironlake and modesetting running Debian stretch. I also see the black dots displayed on the blank plot. I note both the dots and the background issue is fixed by xorg-server 1.19.0. looks like this is fixed in xserver 1.19 with commit c9b8ce73927a43ed82b267d1c1985445f24827cc Author: Mark Yao <mark.yao@rock-chips.com> Date: Fri Sep 30 16:42:35 2016 +0800 glamor: spans: fixup wrong count on glDrawArrays I haven't verified it myself, but believe the other reports, so closing. |
