visual artifacts on (default) printer icon in system-config-printer

Hi, can someone help me to find how to correct this bug (https://bugs.mageia.org/show_bug.cgi?id=14981)? "For the default printer, a green check mark is placed on the printer icon. In Cauldron's version, it shows two check marks (top left and right) and some visual artifacts (bottom half of the icon) on the icon." any clue on what I have to look for ? Thanks
