Closed Bug 1418893 Opened 3 years ago Closed 3 years ago
Display Mask with opacity does incorrect opacity flattening in some cases
Steps to reproduce: 1. Enable WebRender. 2. Go to https://qz.com/ 3. Move your mouse over the big headline text. 4. Wait for the transition to the dark background to stop, and wait a second more. Expected results: The gigantic "Q" in the background should stay invisible while the headline is hovered. Actual results: After the fade animation, the Q appears again.
After the box has faded to white, it should stay white. But it becomes red again.

It's a invalidation problem. I take a look.
