I have spun up a new Ubuntu 18.04 VM for the tests, just to make sure build is clean. I have build Sip-4.19.16 and PyQt5_gpl5.12.1 using Qt-5.12.3 for Python v3 after your response, and this build does not have the mentioned problem. But Python v2 has it. Python versions used are Python 2.7.15rc1 and Python 3.6.7.</div><div><br class=""></div><div>Regards,</div><div>Umit Oztosun</div></body></html>
