I'm afraid I've found a serious bug in Reshade 3 with IL-2 Sturmovik 1946.
Reshade 2 works fine, but Reshade 3 causes a glitch which is known as the "Visibility Sphere" in IL-2.
Note: This is a matured OpenGL game
Pictures tell more than a thousand words, so please see two images below, top is showing Reshade 2 (normal), bottom is Reshade 3 (bug).
Note that Reshade Shaders were toggled off when taking these screenshots to avoid any shader influence.
