Handbrake doesn't work properly with lastest Wacom Drivers loaded

[TRS80]

FYI....

While running Windows 7 Pro (all updates current as of 7/5/17), Handbrake 1.07 and latest Wacom Tablet Driver 6.3.22-6, Handbrake does not appear to launch when clicked. But the program can be seen listed among the running processes -- as though it is running, but the GUI does not show on the screen.

If I unplug my Wacom tablet PTH-451 from its USB port and launch Handbrake, Handbrake loads and runs properly. If I insert the USB plug from the tablet while Handbrake is running, Handbrake crashes and so does the Wacom tablet driver. Took a while to discover why Handbrake was not running properly.

Not likely a HandBrake issue, but something wrong with the Graphics stack on your machine. My hunch would be something is breaking the DirectX, OpenCL or hardware detection API's we call.

You could try a nightly as we recently removed quite a bit of GPU functionality around OpenCL/DXVA.

Otherwise, your only solution I guess is to unplug the tablet as there won't be much we can do about this.

I'm having the same issue. Wacom desktop center open up with a black screen. If I unplug my Cintiq from the computer via it's usb the app opens fine. What is causing this?

Have you spoken with the vendor to ask them what's causing it?

It would be interesting to see if older unpatched windows releases are affected. If they arn't then I still suspect it's the same issue with the recent windows updates around the time W10 Creators was released. Regardless, looks like they are not in any rush to fix it despite it affecting numerous apps.

Just found out about this too. I unplugged the tablet, started up handbrake. then plugged it back in. I got 2 error messages instantly.
Hopefully this will help the dev team figure out what is causing the conflict?
