GUI problems with showcase on Linux

[mgbf]

I'm having some problems while running the showcase (smartgwt and smartgwtee) on Linux. I used Firefox 3.0 and 3.5.5 in my tests.

I can navigate throught the samples without problems for some time (at least 30 minutes), but suddently I start to have trouble with screen refresh, like:
- clicking on a different tab on the View Source window updates the content, but not the selected tab
- changing the active sample keeps part of the old one in the screen
- scrolling grid just updates the bottom lines, the top half keeps unchanged, an so on...

In all cases, an Alt-tab and then geting back to the showcase redraws the screen correctly, but when I interact to the samples the problem continues.

I'm sending as attachment how my screens becames in this situation.

In case it helps, in one of my tests I opened three tabs of the showcase, but used only one of them. When these GUI problems started, I switched to other tabs and I could use normally the showcase without this gui bugs, they were not affected. Also, I used to keep opened the tabs of each sample, when the problem appeared I had 9 tabs opened.

Do you have any idea of why is this happening? Want me do do any other tests? Any know bug related to that?

Thanks,
Matheus

No known issue. Launch the Developer Console (last side nav menu item) and look for any errors logged and post details here.

Actually, we have seen this, but it appears to be a bug in the component used to view syntax highlighted source code (it's not cleaning up iframes reliably) and won't affect real applications.
