Comment 6 for bug 1899270

glxinfo output is attached.

I'm not routinely running anything that needs acceleration. I'm a musician/programmer so primarily audio and code, not even games come to think of it. I did do some work in Blender over a year ago, but I only used this machine for extra rendering work (using the CPU, not the GPU). I just fired it up again and it's behaving properly, though I've no idea whether it's using acceleration.

By the way, the Software Update package is reporting that a new version of Google Chrome is available. Would it be helpful if I held off updating it until you've got to the bottom of this. Or shall I go ahead and check behaviour in the latest version?
