TileQt::updateBackBuffer() applies a translate operation that is never unapplied, this can cause layers to be painted in incorrect positions more or less randomly.

Turned out this patch actually did nothing. It was fluky in my testing that I observed a change. The underlying was solved by merging the patch from bug #105494
