Just write another test http://jsfiddle.net/gv7spbLc/
The expected result is moving line without trailing.
If the result is incorrect, change the flag closePath to 'always' or getContext2d to 'always' to see if the issue is solved or not.

Thanks for looking into it. This test also works fine for me, but still no luck with the charts. Wish I could be more helpful than that!

The test script also works fine for me - setting skip & once.
Seems like the coordinates for clearing pattern are calculated wrong on some systems.
Btw, I have two other PCs, also with win 8.1 and the current Chrome version and the charts work fine on them.
Weird Undecided

The system use assign width to clear the whole canvas before and now it uses clearRect whole canvas, so it width and height should be correct. It shows correct when turn off the hardware accelerate for some users. so I think there is some thing conflict with hardware accelerate.
