The GetDeviceData() failure does indeed seem to happen from time to time on the cw-rx460 and cw-gtx560 machines. But on the QEmu VMs it's very much systematic which is good: it should make it easier to debug.
Also this happened before the move to Debian 10 and the Debian 9 VM did not have the tablet device. So we can rule that and the dual screen configuration out as the cause. I also checked the fvwm configuration which is ok (in particular NO FocusFollowsMouse).
Is there a way to get WINEDEBUG output for a test run on the debian VM?
