With the OpenGLES backend, we use the MSAA render to texture extension. This means that the offscreen textures are multisample and implicitly resolved when sampled from. This implicit resolve does not occur in the blit command used to restore to the onscreen, which can trigger a crash in the GLES driver. In other backends, the onscreen is also multisample and the blit is OK. Fixes https://github.com/flutter/flutter/issues/163304
