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! :eyes:
I investigate this bug and found that it appears only if GIF image
- has only black color and transparency
- puts as background
- need to be smaller than 64×64 px
Have fun! 😀
Also read forum post about this bug.

Hmm. I see no black square.With 150% zoom everything looks normal on:Version 8.02 Build 1272 Platform Linux System i686, 2.6.12-8-386 Qt library 3.3.4 Java No Java Runtime Environment installed
This bug works on Windows version only.
Interesting. Did you file a bug report? 🙂
Of course I did, but can’t give you exact ticket number. :(Anyway, I can fill it out one more time if needed.

this is a funny bug, lol. niiice find, haha. wonder what causes this. whenever this bug is fixed i hope they give us an explaination as to why it happened and what fixed it. this is very odd. 😀
I already reported this bug many months ago. I remind it oftentimes in forums, but nothing.Here is bug number of my report: bug-126808And here is testcase: http://atom.mamto.cz/projekty/opera/bug4/This bug exist from Opera 7.2 and maybe earlier!!!!!!!!
Hello Andrey,I see that you have been very careful and thorough in documenting this problem.Has this bug been fixed yet?I am also very frustrated with some Opera bugs.I spend hours creating test cases but very few people care.I’m not giving up, yet.I think the developers must fix basic bugs timely.Moi otetz rodilcya okolo Kieva.Regards, Jeffrey
Thanks for comment Jeffrey!No, this bug still there – in Opera 9 final. :(I spend many hours to build test cases too. And sometimes they actually fix the bugs. 😉 But anyway at that moment it’s fun for me too – build test cases. :DDo you have links to your test cases? It’s would be interesting for me.P.S. Рад видеть здеть кого-то русскоговорящего! :up:
Does he have to make one blog post to opera developers (olli was one for them) start to look at us ??there are some bugs out there since the beginning and nothing.
Added new site to a list: http://kurafire.net/learn/archive/2005/12/introI don’t believe anymore that Opera developers will fix this in any 9.0x releases. 🙁 So, we will see if they managed to fix this in next major version…
The bug is still here in first Opera 9.1 weekly build :/
Just noticed that new design on digg has icons that appears on black background when zoom != 100%. Horrible!Opera should fix this bug in Windows version ASAP!
…And because I see this bug during around 3 years (since first Opera 7 beta appears)You should update this. I have seen this bug at least since Opera 6.
JuergenJ, no, this bug was introduced in version 7. 🙂
hmm, yes, I tested again and wonder which pretty old bug I mixed up. May be this one? (Since Opera 3)http://www.jeka.info/bugs/font-weight-arial.htmlhttp://www.jeka.info/bugs/font-weight-opera3.png
In Opera 9.5 build 9500 is this fixed. Great. Thanks you!
