    Is there a way to disable tablet support in PD14? It looks like it is causing issues with input lag (clicks are registered too late, drag action starts only after a certain distance, dragging windows is ... odd). And I don't care about pressure support inside the VM, so I'd rather have it emulated as good old plain mouse...

    Hello SergeyS12.
    Pressure sensitivity support comes into play only when the tablet device is attached to Windows directly or when holding the Fn key down while the VM is in focus on a Mac computer with a trackpad.

    For ordinary mouse control, please shut Windows down, open the virtual machine configuration window, navigate to Hardware -> Mouse & Keyboard, select 'Don't optimize for games' for 'Mouse' and disable 'Mouse pointer sticks at window edges' and 'Smooth scrolling'. Close the window now and check for the issue again.

    Not sure if it is correct though that the tablet has to be attached to Windows. If that would be the case, Wacom drivers would take over and show that the tablet is connected, which is not the case. Instead the tablet is "virtualized" as outlined in 14 release notes. In fact there is Parallels digitizer driver that could be disabled, which keeps a mouse working but turns off the tablet input method support completely.

    "Emulated" tablet and mouse/trackpad behave quite differently at the moment, and optimization settings don't have any effect.

    While the issue(s) occurs (very important), kindly generate a Technical Data Report (enable the option 'Attach screenshots and other files' before generating the Technical Data Report) and reply with the report ID number. We'll then investigate.

    Hey,

    The report ID is 287954250

    Here is the best way I can describe the lag issue:

    Tablet:
    https://www.dropbox.com/s/3d6pxovyja9scx3/scroll-tablet.mov?dl=0 - click and start dragging the scrollbar. Nothing happens until the pen moved a certain distance, and after that scrollbar "jumps". Note: the scrollbar is just for demonstration, this happens with every tap-and-drag action

    Touchpad:
    https://www.dropbox.com/s/indx7i74zv0i1l9/scroll-touchpad.mov?dl=0 - click and start dragging the scrollbar - the scrollbar moves immediately with the cursor. Feels smooth.

    This did not happen in PD13, so it feels like the new tablet support had messed up the experience.
