This works for me on debian stretch. Can you provide more information about your system? Hardware / GPU Distribution libdrm version xorg config A backtrace would be nice. The strace isn't very useful. Sure. Let me attach some system/build information and backtrace. Created attachment 127769 [details]

(In reply to Marcus Hoffren from comment #5) > Created attachment 127770 [details] > gdb backtrace Could you recompile Mesa with debugging symbols? The backtrace won't contain much information without it. Try this: mattst88@macbook ~ % cat /etc/portage/env/splitdebug.conf CFLAGS="$CFLAGS -ggdb3" CXXFLAGS="$CFLAGS" FEATURES="splitdebug" mattst88@macbook ~ % cat /etc/portage/package.env/splitdebug media-libs splitdebug.conf and just recompile.

Ok. Recompiling and creating new backtrace. Created attachment 127776 [details]
gdb backtrace with mesa
Sorry for the slow response. The SNB doesn't get turned on very often anymore. I've got mesa-13.0.3 installed and I cannot reproduce. I switched zsnes to 640x480 ODS full screen. Could you try mesa-13.0.5 (latest stable in Gentoo) or the unstable 13.0.6/17.0.2? Sorry for late reply. Still present in mesa-17.2.0_rc5, and has been with all versions before down until, and including mesa-13.0.0-rc1. I tried as well but could not reproduce this on my SNB Mobile (0x126), I tried with Mesa master (commit hash 4009370232), mesa-17.2.0_rc5 and mesa-13.0.0-rc1. I launched zsnes in 1024x768 fullscreen mode and this was on Ubuntu 16.04. setting priority to low, since no one here can reproduce it. Not able to reproduce this on: XUbuntu 16.04 / Fedora Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz Intel(R) Sandybridge Mobile (0x126) mesa 17.2.8 as we tried to reproduce it and couldn't, and there were no any feedback from reporter, closing. Please fill free to reopen in case if you can reproduce it. |

Created attachment 127744 [details] strace verbose log Present since mesa-13.0.0-rc1 Steps to recreate: Launch zsnes in fullscreen mode. Launching in windowed mode, and then switching to fullscreen works as expected. Effect: Segfault (see attached strace log)
