Just wanted to let everyone know: JayDee’s excellent Clean Glass Mod DOES appear to work in MSFS2024, albeit only for unencrypted (i.e. Community-folder-installed) aircraft. I tested it on the LFVR A340, and it blessedly got rid of the scratchy handprint tiling on the glass.
It does still leave the excessive reflectivity intact, so you don’t lose out on all the obscuring reflected glare you’ve come to know and love…
