The colors in the pages tab reflect those in the jpgs imported into indesign. But these colours are not shown in the main part of the main part of the screen. These latter colours are less saturated and the white balance seems to be off, as if pushed to a cooler palette. The screen shots included below show this effect. When the application is first opened, the colours are OK for about a minute or so, and then they are altered as described.

This happens with both 2025 & 20236 versions, ie 20.5.2x64 & 21.2x64
