Also, this isn't true? The blur busters founder (Mark Rejhon) has worked a lot on this exact issue and already has defined shaders and approaches to arbitrary subpixel geometry text shaders in the PowerToys repos (no thanks to Microsoft).
His approach is based on the Freestyle HarmonyLCD subpixel rendering approach which has supported non-striped layouts for over 6 years.
We're currently blocked by Microsoft, who continue to ignore everyone on this issue despite Mark's best efforts. Core Windows shaders need to be modified and he can't really proceed without cooperation, without injecting a security risk for anyone who uses his solution.
