2. see the charts, and compare the charts with that in other browsers or Firefox on other platforms

There should be grey language names vertically lied in each column, and there should be horizontal grey lines for each scale line.

Actual result:
There is no language names nor scale lines.

I cannot repro this in my local Mac. Maybe windows only problem?

Yes, it is. I forgot to mention that, it is also only reproducible when hardware acceleration is enabled and on Windows.

This is a testcase simplified from that image. It seems that the issue is related to mask.

linearGradient in the previous testcase is not necessary. A mask with transparency is enough to show this issue.
