Did I just screw up here big time? I was thinking the joint width is the distance between the top edges of the adjacent tiles but they look way smaller than the regular joints. Plan is to use Fusion Pro grout and the spec says 1/16" and up. Considering going back and widening the grout line with a diamond needle file.

The framing around the window is screwed together, yes, but there may still be some movement. After the finished CBU sat for a while, the inside corners developed some hairline cracks and those had been finished with flexbond (and mesh tape). The outside corners on the front edge seemed ok. There's aquaD and mesh fabric over all of it. Still sound like it's best to grout everything but the window joint? If so, any tips on tooling the grout over those tight joints?
