Comment 43 for bug 81858

There may well be issues with 3d acceleration, but the issue I'm experiencing with Google Spreadhseets and Ubuntu, which is at least in symptoms identical to the issues experienced by others above, is categorically and provably not a 3d acceleration issue.

Under Ubuntu, with unknown 3D acceleration support, Google Spreadsheets crawls horribly. However, if I start up VMWare Server and boot Windows 2000, Firefox and Google Spreadsheets inside that VMWare (which has no 3D acceleration support, at least in my version) is fast as you like. Far, far faster than using Firefox/Google Spreadsheets natively in X.

This may well be a separate issue from that with digg.com, of course. It also may be the case that, if others are not experiencing such a slowdown with 3D acceleration enabled, it may be that the 3D acceleration is mitigating the effect of a bug; for example, if something is causing excessive overdraw, the 3D acceleration may render the bug unnoticable, and this is masking the underlying problem.

I'm behind the times... I had no idea hardware compositing even existed under Linux or Windows...
