Description Roman Jarosz 2012-09-14 17:32:05 UTC

Hi,

using latest git source 8e9d64203428b344433ac8f86dc1f06d2c32529a I see rendering corruption using Opera with SNA acceleration, it looks like the screen isn't redrawn.

Steps to reproduce:
1. Start Opera browser
2. In menu goto Tools->Preferences...
3. Select "Advanced" tab
4. Choose "Content" on the left side
5. And click "Plug-in Options..." button
6. Move the "Plug-in Options..." dialog down, and the parent window isn't redrawn correctly.

It happens also to other KDE windows if I open them on top of broken Opera window.

Using KDE without composition.

I'm using Opera 12.02 build 1578

The bug only occurs when using the Oxygen toolbars, was using Plastique because of an earlier bug and wondered why it worked.

    sna: Only discard CPU damage if we completely overwrite its extents
    
    If we are performing a clipped copy, then we must be careful not to
    completely discard the CPU damage as it may not be entirely replaced.
