No it's not a known issue.

The kernel does not sends the touch begin and touch end information, thus the device is not working :( Can you compile and install hid-recorder from http://bentiss.github.io/hid-replay-docs/ ? I would need a hid-record of your touchscreen so I can figure out why the kernel does not handle it properly.
