Description
When using GraphicsDevice.GetBackBufferData in DesktopGL while a RenderTarget2D is applied, the returned texture data is ordered incorrectly. When it is stored in a texture without re-ordering, you can see that the data is stored "upside down".
This issue does not occur when there is no applied render target.
The following two screenshots were taken in a test app. The left side of each screenshot is the original drawing, and the right side is an overlay of a texture generated from getting the drawn data from the back buffer. The first screenshot was taken without a render target applied, the second one was taken with one applied.
What version of MonoGame does the bug occur on:
- MonoGame 3.8.0.1375-develop
What operating system are you using:
- Windows
What MonoGame platform are you using:
- DesktopGL
