XYPad Mouse Pointer Vibrates in Cubase 14

Dear,

When running VST3 plugins in Cubase 14, dragging the mouse over the XYPad causes the pointer to vibrate. This occurs most noticeably on Audio Tracks when the plugin’s ASIO-Guard is enabled. It does not occur when clicking the mouse or during parameter automation.

Environment: Windows 11, VSTSDK 3.8.0, Cubase 14 Artist. Does not occur in other DAWs like VST3PluginTestHost, Reaper, or FL Studio.

Please advise if you know a solution.

The created plugin and source code are available below.

suzumushi0/SoundObject_binary: SoundObject binary distribution.
suzumushi0/SoundObject_source: SoundObject source code distribution.

Thanks,
Muneyoshi Suzuki
