Initial rending of windows appear blank but when rolling mouse over it artifacts begin to be drawn. Makes Thunderbird unsable. However when running the official Mozilla build http://download.cdn.mozilla.net/pub/thunderbird/releases/52.2.1/linux-x86_64/en- GB/thunderbird-52.2.1.tar.bz2 on the same system, no such errors occur. Suggest you compare the two builds and discover what has changed.
