Created attachment 60909 [details] Screenshot of the return of the glyph (cache(?)) corruption The funny glyph problems and weird "looks-like-a-broken-wrapping/modulo" rendering in Firefox seem to have come back at some point. At least the latter was fixed by Chris earlier this year. Unfortunately I am unable to bisect, as it seems the (somewhat) older checkouts of xf86-video-intel don't compile with this current Xorg/kernel/etc stack. As an added bonus, some videos demonstrating the problems in Theora/OGV format: http://tnsp.org/~ccr/intel-gfx/ Not a very helpful report, I know. :/ -- Window manager: WindowMaker 0.92 (also present with Compiz, so probably not WM related) -- chipset: 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) -- system architecture: i686 / 32bit -- xf86-video-intel: (latest) GIT 7e09babb3e9e23882db30ee7d0c22c503962faa9 -- xserver: X.Org X Server 1.12.1 from Debian unstable -- mesa: 8.0.2-2 from Debian unstable -- libpixman: 0.25.2-1 -- libdrm version: 2.4.33-1 -- kernel version: 3.3.4 (vanilla from kernel.org) -- Linux distribution: Debian Testing aka Wheezy -- Machine or mobo model: Asus P5KPL-CM -- Display connector: VGA
Hi Matti, can you try and see whether this is the minimal required patch: diff --git a/src/sna/kgem.c b/src/sna/kgem.c index d519ed6..b3ac31f 100644 --- a/src/sna/kgem.c +++ b/src/sna/kgem.c @@ -3978,7 +3978,7 @@ struct kgem_bo *kgem_create_buffer_2d(struct kgem *kgem, assert(width > 0 && height > 0); assert(ret != NULL); stride = ALIGN(width, 2) * bpp >> 3; - stride = ALIGN(stride, 4); + stride = ALIGN(stride, 64); DBG(("%s: %dx%d, %d bpp, stride=%d\n", __FUNCTION__, width, height, bpp, stride));
commit f4c34e9ab32f31669896b8f626195827a85af337 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed May 2 19:09:10 2012 +0100 sna: Bring back the minimum alignment for G33 The underlying cause is still not fixed. It should be possible to use the much laxer alignment for single-stream linear. Still no idea how I fail to convince the GPU to drop the depth buffer.
