When I will have time I will check OpenCanvas - that might be something not related to tablets (unless you have this happens only when the tablet it plugged into the computer?).
However as I understand you have no stack overflow but also no tablet support in Flash? There are two problems I know of - on laptops with touchpads and once I had a problem with a hot-plugged tablet - I had to restart the computer with the tablet plugged during the boot for Wine to be able to open it. If this is not the case could you attach a WINEDEBUG=+wintab32 log?
