Black artifacts appear on screen, appears like a punched card. This shows up well in firefox. These marks move when scrolling but disappear when scrolled off and back only to be replaced by marks in other places. See https://bugs.freedesktop.org/show_bug.cgi?id=68410 for discussion. I've downgraded the driver and the problem goes away. Reproducible: Always Steps to Reproduce: 1.use firefox to look at a page with lots of text. The apache docs for mod_proxy seems to reproduce it well 2. 3.

Does the patch mentioned in https://bugs.freedesktop.org/show_bug.cgi?id=68410#c12 reduce the amount of display corruption on your system?
*** Bug 486924 has been marked as a duplicate of this bug. ***
I'm not really sure 486924 is a duplicate. The screen garbage I saw was not small black rectangles. It rather looked more like recycled trash from other parts of the screen.
I've the same issue with x11-drivers/xf86-video-intel-2.21.15. With some changes for the different code base this fix works for me: https://bugs.freedesktop.org/show_bug.cgi?id=68410#c42 (I've nevertheless masked xf86-video-intel-2.21.15 now, since this version is also crashing my hard resetting in a very curios way. I'll open a new bug for that.) Here the modified version for xf86-video-intel-2.21.15 I'm using. Be warned that I do not really understand what I changed and it may break something else: --- a/src/sna/gen7_render.c +++ b/src/sna/gen7_render.c @@ -1074,6 +1074,7 @@ uint16_t wm_binding_table) { bool need_stall; + bool need_flush; assert(op->dst.bo->exec); @@ -1086,20 +1087,23 @@ gen7_emit_wm(sna, GEN7_KERNEL(op->u.gen7.flags)); gen7_emit_vertex_elements(sna, op); - need_stall = gen7_emit_binding_table(sna, wm_binding_table); - need_stall &= gen7_emit_drawing_rectangle(sna, op); + need_flush = gen7_emit_binding_table(sna, wm_binding_table); + need_stall = gen7_emit_drawing_rectangle(sna, op) && need_flush; + + need_flush |= sna->render_state.gen7.emit_flush; if (kgem_bo_is_dirty(op->src.bo) || kgem_bo_is_dirty(op->mask.bo)) { gen7_emit_pipe_invalidate(sna); kgem_clear_dirty(&sna->kgem); assert(op->dst.bo->exec); kgem_bo_mark_dirty(op->dst.bo); - need_stall = false; + need_flush = need_stall = false; + } + if (need_flush) { + gen7_emit_pipe_flush(sna); } if (need_stall) gen7_emit_pipe_stall(sna); - - sna->render_state.gen7.emit_flush = GEN7_READS_DST(op->u.gen7.flags); } static bool gen7_magic_ca_pass(struct sna *sna,
I see the same behaviour on my integrated HD Graphics 4600. The black rectangles are 8x4 pixels. Furthermore I see strange substitions of characters in various programs and fonts. I tried recompiling the driver just to make sure it wasn't some compatibility issue because of xorg-server upgrade or something but it appears to have made the problen even worse. Now I can crash the server when highlighting text and making certain keystrokes.
This was mentioned on the mailing list (chris?) as a known issue -- it's a hardware bug in ivy/etc they needed to come up with a workaround for.
According to https://bugs.freedesktop.org/show_bug.cgi?id=68410#c79 the workaround is this one http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=12f4c48d39b939a3a26a1504910b5f16ee6c86b8
According to freedesktop bugzilla this bug was fixed in "xf86-video-intel 2.99.907-2". I emerged the newest unstable version (2.99.914) it fixed the problem for me. Any chance to tag *.907 or newer version as stable?
I had the same problem here with the current stable (2.21.15). After emerging the latest masked version 2.99.917, now everything seems fine. Using a HP EliteBook 840 G1 laptop with Intel HD Graphics 4400. lspci says: "Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)"
I have this issue as well. I'm not sure when exactly it started, but I think it was after I enabled vaapi USE flag.
Small black rectangles is kind of the most common failure mode. People are almost certainly seeing different bugs. In any case, test a new version of the driver. If it's not fixed, please file a bug upstream at bugs.freedesktop.org. We're not prepared to fix driver issues that aren't fixed upstream.
