Rendering bug in Opera 8 and 9 TP1
While developing CSS + JS driven navigation I struck with buggy Opera 8 and 9 TP1 behaviour - some parts of menu doesn't redraw. BTW Opera 7 do it right along with IE 5.5, IE 6, Firefox and Safari.I tried to include in JavaScript code some kind of empty cycles, timers to solve this redrawing thing, but nothing helps.
I posting here because I think that is bug in Opera 9 TP1... So, please confirm. I tested on both Mac and Windows Opera 8.5.
Also I would appreciate any workarounds to this problem.

What am I looking for, specifically? So far as I can tell, it works fine in 9.0 TP1.

I can confirm that the repainting is not very good -- sometimes the bottom border of the tab is clear, sometimes it is half-rendered. Even the color transitions are not complete.
Please report this problem at Opera's Bug Tracking system and post the bug number (without the email address part) here.

Bug report #191898 was submitted.
Anyway, as I said before - any known workarounds is highly appreciated.
Also, feel free to comment on this navigation itself in my journal post.

Reason I didn't see any problem is I'm using Linux, by the way. As you reported that it works fine in Mac versions, it would work fine in the other UNIX versions (Linux, Solaris, FreeBSD).

I think that this bug also not existing in versions for UNIX...
Edit: Actually Mac version has the same buggy behavior as Windows version...

I created some styles that work without JavaScript. That styles have "no JS" string at the end of the name of style. So, if you turn off JavaScript with one of such styles, bug is gone.
Reason why I use JavaScript is accessibility. I dont want behaviour when menu is gone when you just move mouse a little off the menu.

The only issue I see in the "thick border" examples is that the image for the current option is the wrong size. Everything is rendered properly, and properly erased when I move over a different selection.

What you see is incorrect redrawing of styles and I repeat myself again - it occurs only with JS on.

In Opera 8.5 I can confirm this buggy CSS, but CSS has been fixed in Opera 9.0. In Beta #8393 I get the same view as in IE and FF while hovering through the items.

Do you mean the small cube in the left corner of one item? This does only appear in Opera, but it´s moved after moving the mouse. No idea what causes that...

Look at the top edge of Documentation tab: opera-redrawing-bug.gif
This "something" appears after I move mouse off the tab (to the top)...
Oh... and as I told before it's a regression from Opera 7 where this menu looks and behaves completly fine.
