When the display profile changes, i.e., when using automatic profile switching when room lighting changes (Spyder), document pages and any items on the pasteboard disappear. The rest of the UI remains the same.

The 'fix' suggested elsewhere is to turn GPU preview off. However, when you do that, clicking on the document/pasteboard makes both flash white and can also make the document jump leftward to the edge of the window.

The only real fixes are to close and reopen the document(s) or restart InDesign.

And just in case anyone is tempted to suggest I stop using Spyder or any other display calibrator, please don't.
