Sdkmanager window size

I just downloaded SDK Manager and find the window size does not reflect the size of the interface and the “continue” buttons and accepting the license checkbox are not visible in all screen resolutions. I am using Ubuntu 18.04. If I have the full screen resolution of 3840x2160 I can’t see the button/checkboxes. If I reduce my resolution then i eventually can see enough of the checkbox to agree to the license.
