i am back with another fp16 blending problem.
i render lines. use ONE, ONE blending (from -2047.0 up to 2048.0). color is (1.0, 0.0, 0.0, 0.0). after rendering all lines i get the max value from red channel (through reductions. i get same values with reading back the texture). the problem is the max value, it is many times incorrect, some times twice as high, as it should be. when i resize the window, the max value is “jumping” up and down. ay ideas how this could happen?
