Display problem Draftsight/Mojave Macbook Pro

Hello everyone,I just bought a new Macbook PRO 13 inch with Mojave, and I installed the latest free version of Draftsight I have been using for a long time on PC. I have a display problem, all texts, lines and drawings are slightly blurred (even all the content of the application). Is there a known compatibility issue between Draftsight and the latest version of Mojave? Would someone have the solution? Thank you for your help.
