Render Targets ignore RenderTargetUsage parameter

1

I recently started updating to MonoGame 3.6 (boo technical debt!) but I’ve noticed that none of my “games” that use rendertargets are rendering correctly… It seems that between MonoGame 3.5.1 -> 3.6 the RenderTargetUsage parameter is being ignored.

This is a DesktopGL tool that worked perfectly in 3.5.1, but after updating to 3.6 clears the screen contents to black. I specifically have the following code in the app:

//When using render targets, don't clear the screen!!! GraphicsDevice.PresentationParameters.RenderTargetUsage = RenderTargetUsage.PreserveContents;
which is being ignored.

halp!

Yeah idunno, somewhere in the guts of the GL code the RenderTargetUsage is being reset to DiscardContents… I figured out the workaround for now is set to PreserveContents after the redner target is created.

Can you open an issue on GitHub for this? Not sure if it’s still in develop, but should be checked.
