I got tired of flash bugs in chromium too, and started to develop a browser extension for better displaying the charts (pure-js solution). For now, it replaces statistics and summary diagrams on the game statistics page.
You can install it from chrome webstore:

If you have some ideas, what thing needs to be improved, or can help me with charts' design, you're welcome to open an issue on github:)
