Hi,
The distortion in the Windows Photos app is caused by GPU rendering or color profile conflicts, not by the image itself. Other apps display the image correctly, which confirms the issue is with Photos using hardware acceleration and color management.
What I suggest is :
Disable hardware acceleration in Photos settings.
Reset or remove custom color profiles in Color Management.
Update or clean-install your graphics drivers.
Turn off HDR temporarily and test.
If the issue persists, use an alternative viewer until Microsoft releases a fix.
I hope this helps!
