Package: iceweasel
Version: 44.0-1
Severity: important
Dear Maintainer,
After upgrading sid/experimental the iceweasel acceleration enable feature is not working good
if using fbdev xorg configuration with swrast (xinerama setup). It hangs the CPU near the 100% and all the colors are in a wrong
RGBA order. Color Swap? Bad RGBA ABGR conversion? This setup is a PowerPC BIG ENDIAN machine...
The only way is to use the accelerated video driver (i.e. radeon or nouveau in my specific setup)
or
disabling the hardware acceleration feature in the iceweasel preferences section
The biggest issue in this configuration is I am unable to upgrade either kernel (due to a binutils bug on PPC64 architecture),
so I can not say for sure if it happens with the 4.4.0 drivers.
Right now I am using the 4.1.0-2 kernel version and the lastest xorg drivers. (updated today)
