Been trying to adjust the paper size on xdrawchem but it will not change from the default startup size. Tested the version supplied in the ubnutu repos and tried compiling from the source still get the same result. Only clue I have to what is going wrong is this error shows up in the terminal when trying to change paper size. qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 1159, resource id: 11457568, major code: 40 (TranslateCoords), minor code: 0 screen
