Opera 12.10 + Ubuntu 12.04 and canvas problem... and more

Question

linux

Opera 12.10 build 1652
Ubuntu 12.04 64b The
github

Canvas example is buggy. I also saw a problem with the background (checked - not canvas), but lost the link to the page.
So I wanted to find out if I have a problem or is it Opera's problem?

Answer 1

I understand that the issue has already been resolved, but I wanted to note that I encountered exactly the same problem, and I attribute its root cause to the video card drivers (in 12.10, the work of old NVidia under proprietary drivers broke, so I switched to open)

Answer 2

Ubuntu 12.10 x64, Opera Next 12.11 - everything is fine, Opera Next 12.10 also worked fine, I do not use stable versions.
