Please fix broken cockpit reflections in many planes - they now have become show-stopping

[cfrag]

For a couple of years now, many modules (off the top of my head: Huey, Hip, Tiger) have been afflicted with a show-stopping rendering bug that makes them un-flyable because the glass becomes opaque. We could live with ED's slow response to fix this because a rather simple fix to the glass.hlsl  (shader file) allowed us to fly these models again. Hooray for the community.

Now, unfortunately, the shader files have become off limits, as now changing them taints your install. A DCS Installation that uses the glass shader fix fails the 'purity' test, disallowing login to most servers. 

This means that I now need to revert to stock glass rendering, and the Huey, Hip and Tiger are no longer viable to fly (the cockpit turns opaque at certain angles to the sun). So, please ED, after more than two years, please fix the long-standing reflection issue to allow me to fly my paid-for modules again. Or allow fixes to the glass shader to not taint my installation. Either works well for me. Losing three (probably more, need to check) modules at once feels very disappointing.
