When using Lossless Scaling for the first time on a video after the system starts, the screen turns yellow and becomes brighter. This issue occurs with both online videos (e.g., on webpages) and local video players. No matter how I adjust the various options in Lossless Scaling (e.g., enabling/disabling frame generation, scaling, or tweaking its settings), the problem persists. However, once I apply Lossless Scaling to a game, and then to a video, the issue no longer appears. Could anyone explain why this happens and how to fix it?
