Sometimes while playing some flash videos I see errors on stdout of Xorg: intel_bufmgr_gem.c:1169: Error writing data to buffer 770: (0 706560) Bad address . System environment: chromium 5.0.375.127 flashplugin 10.1.82.76 chipset: GMA 5700MHD system-architecture: 32-bit (i686) xf86-video-intel: 2.12.0 intel-dri: 7.8.2 xorg-server 1.8.1.902 libgl: 7.8.2 libdrm: 2.4.21 kernel: 2.6.35.3 linux distribution: archlinux i686 current machine or mobo model: Lenovo ThinkPad T510 NTF6WRT display connector: none Steps to reproduce: 1. Open chromium (I can't reproduce the problem in FireFox) 2. Go to http://www.tvigle.ru/category/cinema/serdce?video=477593 3. Start watching the great movie "Heart of a Dog" 4. Change the quality of the playing movie to HQ and then to SQ some times: 4.a click on "КАЧЕСТВО" ("QUALITY" in Russian) player button (which is located right after the player's volume control) 4.b click on HQ or SQ 5. Take a look at standard output of Xorg: you'll see a lot of errors like the one at the beginning of the bug report.
