https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236003 Samy Mahmoudi <samy.mahmoudi@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |samy.mahmoudi@gmail.com --- Comment #52 from Samy Mahmoudi <samy.mahmoudi@gmail.com> --- Hi, I had set Option "DRI" "3" on two systems (Sandy Bridge, Ivy Bridge) without setting LIBGL_DRI3_ENABLE properly. I recently upgraded the Ivy Bridge syst= em, so that the recent changes in graphics/mesa-libs triggered DRI 3 activation. Here's what now happens: After some inactivity, pressing a key powers on the monitor but the screen keeps displaying a previous state which is anterior to the last state I let= the system in before being inactive (on the Ivy Bridge system, that screen is t= he SLiM login manager background picture). Mouse cursor moves are still visibl= e, keyboard presses and mouse events are still received, but nothing renders on screen: I can continue to use the system but can not see what happens. The = only way to resume normal rendering is to move my mouse to a corner which activa= tes the Compiz plugin Expos=C3=A9 or to switch between workspaces with another = Compiz plugin via a key combination.=20 By trial and error on the two systems, I have come to the conclusion that t= his non-critical problem only happens with the combination of intel and DRI 3 a= nd Compiz. By the way, I noticed the Sandy Bridge system shows 8200 FPS in glxgears, whereas the Ivy Bridge system (HD 4000, xorg-server-1.20.8,1 and mesa-dri-18.3.2_10) only shows 7600 FPS. I need to upgrade the Sandy Bridge system to see if it keeps an advantage over the Ivy Bridge system. If it do= es not, that would possibly mean that a performance regression happened somewh= ere. The Sandy Bridge system: ThinkPad T520, HD 3000, 12.0-R with xorg-server-1.18.4_11,1 and mesa-dri-18.3.2_3 The Ivy Bridge system: Optiplex 7010, HD 4000, 12.1-R with xorg-server-1.20.8,1 and mesa-dri-18.3.= 2_10 Keep up the great work Jan! --=20 You are receiving this mail because: You are the assignee for the bug.
