981234 - Hardware acceleration with Intel driver creates corrupt buttons

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[Gabriel Souza Franco [:gbs]]

Attachment: Button after opening a new window

Graphics Adapter: Intel GMA 4500MHD (Mobile 4 Series Express)
Driver version: 8.15.10.2869

When running with HW acceleration, Firefox buttons will become visually corrupt. The corruption appears on some elements only, e.g. the disabled favorite star or the hovered back button. I couldn't totally reproduce on a clean profile, but smaller corruptions were visible. No content images seems to be affected.

Do you reproduce this on the stable version - Firefox 27 ?
If not, would you like to help further and find a regression range ? There is a tool for that - http://mozilla.github.io/mozregression/

Yes, I can reproduce, albeit on different elements. This screenshot was taken after maximizing the window a few times, which made the button look like this. Note the broken inner shadow in the Firefox menu, it happens regardless of maximizing it or not.

Further info: I can trace back this issue as far as Firefox 17.
Sadly, I am not able to compile Firefox with my machine, so I cannot help refine the regression range more.

Use mozregression for that:

In your case, pick any date sufficiently far back in the past as the starting point, like 2008-01-01 or so.

Is this still a problem?
