All sample code in the Python Pyglet library suffers from terrible text corruption, caused by the inability to erase the background between rendering sequential font glyphs, resulting in leftovers from previous letters mixing with the image of new letters.
This is because it attempts to erase the background by calling GdipGraphicsClear() with ARGB color 0x00000000 (completely transparent black), and in our gdiplus alpha blending that into the background has no effect. It should be using CompositeModeSourceCopy to overwrite the background with that brush instead.

Can you split off the implementation of CompositingModeSourceCopy into a separate patch?
