Adobe Flash Bug still not fixed for integrated GPU (Intel HD Graphics 2000)

Hello, i opened a bug report here: 875606 -  Intel HD Graphics 2000 - Rendering Bug - Flash Game -  chromium -  Monorail
There was no further investigation from google it seem... they said it's mostly an error from adobe flash developers, I would think it is because the rendering works fine on Mozilla firefox, but any chrome based browser doesn't, half of the textures are rendered until i "hover" the textures with the mouse, it's bugged as hell which make it impossible to play adobe flash game using any chrome based browser...

Did you drop the legacy support of this old gpu ? if yes, what the hell ?
This issue has been around for years and it's still not fixed...

This time for real, can you investigate the issue please ? thanks.
