browser content or 3D applications / games) are no longer drawn (you cannot see the application).ģ) Nothing is drawn anymore (screen is black).
There have been 3 cases detected thus far:ġ) Everything works as before, but with minor restrictions on the available resolutions.Ģ) Window contents that are drawn hardware-accelerated (e.g. In this case, the graphic driver shall decide what it wants to do when the monitor is not detected. Unfortunately, there are some monitors that will only pass their data to the graphic card when they are turned on/have power. The monitor itself does not need any power, as the HDMI / DVI / VGA cable itself provides enough power. Hope this helps anyone else with the same problem.ĮDIT: Further testing shows that you can enable an Aero theme, then go into "Performance Information and Tools" -> "Adjust Visual Effects", and then safely disable anything except the two options shown below.Typically, monitors or notebooks display shall report their data (such as what resolution they support) to the graphic card once they are connected. My options at this point are to either nuke 64-bit and install 32 (nope), or live with it and just enable an Aero theme before launching an OpenGL game. > choose an Aero theme (like "Windows 7", "Architecture" etc) to turn on Aeroglass compositing, and suddenly OpenGL starts working again. Try this: Right click the Desktop -> Personalize. by using a Windows "Classic" theme, or disabling all Visual Effects for maximum Performance. But, it ONLY happens when I have Aero disabled - e.g. even an updated, modded driver like Chell 1.8b exhibits the problem.
This appears to be a combination of Windows 7 (specifically, 64-bit) display compositing, and Intel's OpenGL support on GMA cards. Actually, I found other OpenGL applications that failed with the same symptoms, which hinted that it was more widespread than just a GoldSrc issue. I can provide more info if needed - any kind of GL or other dump logs.Īfter much digging, I've found a solution to my problem. Changing desktop color depth (both 16 or 32) does not help. Disabling Steam Overlay also does not help. Compatibility mode settings do nothing (disable compositing, run as admin, previous Windows version.). No variation of -nomsaa, -nofbo, -gl, -window / -full, -widescreen, -w / -h seems to have any impact. It's not so much a crash, as just a failure of the video renderer. Symptoms are a "black screen" (in full-screen) or a "see-through" window (in windowed mode) on startup. Maybe the GL handle / context is getting lost somehow and the game is unable to update the screen any more. sounds while moving the mouse around) - just the display portion is gone. The issue seems to be that the window opens, but OpenGL is unable to "draw into" it. Windows 7 64-bit SP1, Intel GMA950 graphics with latest driver v.
