A Mosaic appears when a GPU-accelerated H.264 video is played quickly

When I use PR to play the H.264 format video quickly drag and drag will produce a lot of mosaics, there is no such problem when exporting quiketime MOV, this problem has troubled me for a long time, have friends encountered this situation

Try turning off Hardware encoding in the Video tab of the export settings.

Thank you for your reply. The problem has been solved. Thank you very much. But I still have a few questions if you could answer them
1. What causes this and why does it occur
2. Tried and found that the software accelerated rendering output will be much slower than the hardware, is there a way not to turn off the hardware acceleration so that the output video does not form a Mosaic when the quick preview
Finally, thank you for your generous reply. I sincerely appreciate it

1. Sorry, but I don't know why, only what.

2. You can try updating or rolling back the graphics driver.
