--- Comment #4 from Thiemo Mättig <thiemo.maet...@wikimedia.de> --- The issue is caused by the combination of the SVG background and the border-radius. One solution can be seen in 2b8f46c6. An other solution is to remove the CSS border completely and draw the border in the SVG instead. I once tested this and it works fine in all browsers including Opera 12. Personally I'm oscillating between two extremes: * Don't reinvent the wheel. A checkbox is a checkbox. All CSS hacks (opacity: 0, empty clip regions) to force individual styles on otherwise native form elements are horrible and should have never been invented. * Opera 12 is dead. It's performance on sites like Twitter is horrible. People should just stop using it. I did. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list Wikibugs-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
