The OSGText animation (README.osgtext) doesn't play nice with shaders.<ref>https://forum.flightgear.org/viewtopic.php?f=87&t=37429&p=376110#p376110</ref>

Another way to describe the bug is ‘make text animations work correctly with the Effects framework’. Because osgtext always uses a shader (now), and shaders cannot be combined, we have to find a smarter way to do that. But the fact that osgtext didn’t work correctly with Effects has always been there. So there is no upstream fix possible: we have to change what we’re doing on our side, but that will risk some aircraft compat issues. The patch we’re applying is to restore things to how they looked before, but it was still broken, just less obviously.<ref>https://sourceforge.net/p/flightgear/mailman/message/37150030/</ref>
