Malevich Black Square in Opera
Wednesday, 14. September 2005, 01:50:10
Today I want to present one of my favourite Opera bugs in fun way. And because I see this bug during around 3 years (since first Opera 7 beta appears) I want to give this beatiful bug his own name - Malevich Black Square bug. 
So, first of all test page where we can see four Acid Smiles
Two of them (first and third) are images and other two are DIVs with image set as background.
Now funny part. Where Malevich Square here? Just change zoom on the page in your Opera browser or print out the page (needs Print Page Background option checked).
Last Acid Smile now will appears as black square!
I investigate this bug and found that it appears only if GIF image
Have fun!
Also read forum post about this bug.
