7.0.361.1version 8K video problem

[qinjianzhanqing]

Hello, the version I am currently testing is 7.0.361.1. I tried playing an 8K video (7680 * 4320), but it stuttered during playback, as if I was constantly switching between playing and pausing. There was no problem playing 4K videos. There is no problem playing 8K videos using version 4.0. You can find an 8K test video to reproduce it (I have tested several 8K videos and they are the same). Could you please take a look at the new version? What is the issue with this?
