--- Comment #13 from Rafał Mużyło galtgendo@o2.pl --- On a semi-random note: for quite awhile, I've been locally using a trivial patch, that changed in dlls/windowscodecs/bmpencode.c '#if 0' to '#if 1' for the line with GUID_WICPixelFormat32bppBGRA.
That was needed in some random game to get some things to display.
Perhaps that part needs another look too.
