HDR video overlaps other windows and cursor

If you enable HDR in QtQuick (e.g. by setting environment variable QSG_RHI_HDR=scrgb) and also enable HDR in system settings some videos start demonstrating weird side effects by being shown on top of another overlapping window (from different application). This behavior is not reproduced for all videos but mostly noticeable with some HDR ones but non-HDR videos are also affected.

By far I saw this behavior only on NVIDIA GPUs (RTX 2080 and RTX A2000) and not on AMD (RX 6600).

Also the same videos don't have this behavior while using Windows Media Player or VLC. Seems like the problem is somewhere in combination of how Qt does things under the hood and Desktop Windows Manager (DWM) since it affects windows from other applications.

This behavior is also only present with FFmpeg backend. I guess the reason for this is that WMF backend does not implement HDR feature since HDR videos play as regular ones.
