--- Comment #7 from Martin Gräßlin <mgraess...@kde.org> --- This might be a driver issue. The hardware is not really the newest and what the driver reports is rather uncommon. There is not many Intel devices reporting us OpenGL 2.1. This is something I find rather suspicious. In case it happens again: please check also dmesg, /var/log/Xorg.0.log and /var/log/messages. It might be that you find some "hung gpu" messages there. -- You are receiving this mail because: You are watching all bug changes.
