[Bug 1212455] Re: 8086:2562 Flash 11.2 content displays in shades of green and purple only, and in a horizontally compressed space
Good news -- Daniel Vetter from the upstream maintainers list responded
to the email with the more descriptive SUBJECT.
He wrote:
Still a flash bug. This commit simply enables rgb555 in the kernel,
which sna likes to use on gen2/3. Flash is just too dense and always
presumes xrgb8888.
Adding
Section "Screen"
Identifier "igd"
DefaultDepth 24
EndSection
to your xorg.conf will work around.
-------------
And doing so here did successfully work around the behavior for the
machines I reported on.
I note for other users that just the snippet above in an otherwise blank
xorg.conf will do. And many users, like me, will have no existing
xorg.conf but will have to create one, such as I did at
/etc/X11/xorg.conf (though there are many other locations where X will
find the file).

Title:
8086:2562 Flash 11.2 content displays in shades of green and purple
only, and in a horizontally compressed space
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
In my testing with the Intel driver using its default acceleration, what works:
- Flash 11.2 works on Quantal with the 3.5 kernel
- Flash 11.2 works on Raring with the 3.5.0-17 kernel (though it boots to a low-res desktop with a frozen pointer)
- Flash 11.2 works on Raring also with the 3.6.11-030611 or 3.7.10-030710 mainline kernels
- Flash 11.2 works on Raring with the 3.8 kernel (in Chrome)
what fails:
- Flash 11.2 fails on Raring with the 3.8 kernel
- Flash 11.2 fails on Raring with the latest mainline kernel, 3.11.0-031100rc5
- Flash 11.2 fails on Saucy alpha 2 with its default kernel
Disabling Flash *hardware* acceleration altogether (via R-click in the
Flash display window: Settings: General tab) did not fix the problem.
WORKAROUND: Setting the Intel driver's acceleration method to UXA
rather than its default SNA *always* fixes the Flash problem, but
causes a garbled login screen under LightDM that so far has no
workaround.
I also tried one possible fix for the default Intel SNA acceleration using the TearFree option. I created /etc/X11/xorg.conf.d/20-intel.conf with contents:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection
But this had no effect.
