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). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1212455 Title: 8086:2562 Flash 11.2 content displays in shades of green and purple only, and in a horizontally compressed space To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1212455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
