Hello,

I'm trying to play a video in VR mode using HEVC and DASH SRD as follows:

`gpac -i DoiSuthep_dash_22_50.mpd#VR @ compositor @ vout`

But after a few seconds the video seems to have colour conversion issues as shown below:

The manifest was made following  [this](https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide) tutorial. It has two qualities and it seems that the problem happens when it has a quality change, but I am not quite sure.

I have found a similar issue #1919, but his solution did not work for me.

Any help will be very appreciate it.
