Windows XP, any Intel(R) GMA 3100 GPU 2. attempt all blacklist-disabling and hardware accel. enables 3. observe still no 2D canvas acceleration What is the expected behavior? The Intel(R) GMA 3100 chip's latest driver 18.104.22.16818 is from Jan 2010. Chrome should be able to hardware accelerate the 2D Canvas. What went wrong? Even ignoring all blacklisting the rest of the features obtain hardware acceleration but not the 2D canvas Canvas: Software only. Hardware acceleration disabled. Compositing: Hardware accelerated on all pages 3D CSS: Hardware accelerated CSS Animation: Accelerated WebGL: Hardware accelerated WebGL multisampling: Hardware accelerated Flash 3D: Hardware accelerated Flash Stage3D: Hardware accelerated Texture Sharing: Hardware accelerated Video Decode: Hardware accelerated Video: Hardware accelerated Panel Fitting: Unavailable. Hardware acceleration disabled. Force Compositing Mode: Hardware accelerated Did this work before? N/A Chrome version: 25.0.1364.97 Channel: beta OS Version: 5.1 (Windows XP)

This is working as intended. Since we have no way to recover from context loss on XP, and it happens quite often (e.g., when the screensaver kicks in), we cannot ensure that the canvas's contents won't be lost.
