Bug#710182: iceweasel: New Google Maps unusable due to unreadable fonts (Intel graphics)

[Bart-Jan Vrielink]

Package: iceweasel
Version: 21.0-1~bpo70+1
Severity: normal

Dear Maintainer,

When trying out the new Google Maps, which seems to rely on 3D accelerated graphics (webgl?) I notice that the font
used is completely unreadable (it's a black bold font where the individual letters are too close to each other to
be able to read them.
This happens when I use the default Intel graphics (HD4000). If I switch (Bumblebee) to using the NVidia graphics
(GT620M), everything works fine (readable, white font). But, I really don't want to run Iceweasel under this graphics
card as it drains battery too much.
This was also the case when running Iceweasel 18.
