    I have a MacOS 10.6.8 (Snow Leopard Server) VM running with Parallels 19.0.0 on a MacOS 13.5.1 (Ventura) Mac Pro 2019.
    If I double-click on an image file (e.g. ".jpg"). It opens in Preview but I get a totally white window.
    This problem is not new to Parallels 19; I have it for quite some time.
    Pretty much everything else seems to work fine.
    Why doesn't Preview work?

    I understand you are seeing a problem opening certain JPEGs in Preview on your Parallels virtual machine running Snow Leopard. To troubleshoot further, you asked about trying to open one of the problematic JPEGs in Graphic Converter on the virtual machine.

    Testing the image in a different application like Graphic Converter is a good idea to see if the issue is specifically with Preview or something more system-wide. If the JPEG also displays incorrectly or fails to open in Graphic Converter, then it likely points to a more general display problem with how the virtual machine is handling the JPEG image format.

    I can open and view the images with Photoshop on this MacOS 10.6.8 VM.

    I see the same issue in 10.6.8 (not server) running on a 2016 Mac (Skylake CPU), Parallels Desktop Version 19.0.0 (54570), open a screen shot (a png file) created in the VM. Preview.app shows a blank window for the png file. Preview.app is able to view pdfs though. The png file can be opened by GraphicConverter.app 8.8.3.

    Are you saying you can't reproduce the problem yourself? Mac OS X Snow Leopard Server 10.6.x is one of the supported guest OSs. Boot it, press Command-Shift-3 to create a screenshot png on the desktop, open the screenshot png in Preview.app.

    The problem doesn't appear in 10.5.8 or 10.7.5.
    In 10.6.8, the image appears in the Preview.app sidebar but not in the main area. Preview.app crashes if I reduce the window size sufficiently.

    Thanks, joevt. Even I had not noticed that, if you open multiple images with Preview, you can see them in the sidebar while the main window pane is all white.
