Displaying HDR Content requires the GPU to load up multiple layers of an video, wich of course caused longer loading times for the content. So we as developers should starr thinking about creating an better layer delivery timing. During video streams, the RAM can be a good place for video storeback, but this brings the problem with it, that the application that started the video and file stream, have to make sure, that there are no other applications that may use an large amount of ram or a big latency. So it appears logic, that the following error message may get displayed:

Since the GPU cache load was never under 2.4 MB (which is a lot when using the terminal), I assume that the file just was not deleted from the GPU cache and probably was simply loaded on shutdown. Immediately I realized that if it had been a less harmless content that would have led to very unpleasant situations ..... After a search on Google, I found out that other users have the same "problem". </ p> <p> </ p> <p> I wanted to reconstruct the problem, so I just played a video while doing a background mining stress test. The result was very clear: The GPU could not deliver a frame and could not delete it because of a time exception. (A similar problem sometimes occurs with Netflix: video becomes small and the rest of the screen turns green.) The problem can be solved by purging the cache using a graphics discard. You can find the logs below.
