Should this be sufficient to only trigger the workaround on GL driver? Or should
I add this workaround separately for Linux, Android, OSX?

[Ken Russell (switch to Gerrit), 2016/05/09 18:34:08]

This should be sufficient. If one or more of the platforms fixes the bug and we
decide to disable the workaround, we might need to add separate entries, but
let's do that later.
