Scrolling problem with Opera after using Kino2

[vinc17]

After using Kino2, scrolling no longer works correctly in Opera 7.30, in particular the scrolling line by line (page by page is better): some rectangular parts of the screen are not redrawn. Quitting and restarting Opera has no effect; it seems that I need to reboot!

Does anyone have any information about this problem and if it can be solved?

Note: I have a Zaurus SL-C860 with the original ROM (1.40 JP).

TIA,

Vincent Lefèvre.

In fact, there are similar scrolling problems with other applications, like Netfront and Zeditor (but not with Terminal and Qkonsole).

I've noticed that the problem disappears after the screen saver activates or after suspending the Z.
