哇,還有這樣一個地方討論bug...

看了一下

Disabling Azure Content prevents it from using Direct2D from rendering that content.
Disabling Direct2D forces the browser to fallback to Direct3D 9.

FF-19.x / Win7-64bit / AMD Catalyst v13.1 driver (Radeon HD 7850):

Issue isn't caused by facebook pages only, it occurs also while switching between tabs or calling new pages:

If FF hardware acceleration is disabled, no more display issues so far!

我這邊是偶爾(不常)發生,只要change view(F5,切換tab)該症狀就消失
看來AMD跟FF有兼容問題(主要)
總結一下
不限定7xxx,
6系列也有案例
不限定FF,
chrome也有(但也有人沒有)

12.10,有人是說ok,我也懶得測了

最後,還是把setting enable了
