Description Benjamin Roe 2003-09-26 19:59:33 UTC 
Version:            (using KDE KDE 3.1.3)
Installed from:    Gentoo Packages
Compiler:          gcc-3.2.3 
OS:          Linux

If I "tail -f" a file that is growing in a konsole window, so that the output causes the konsole window to scroll, and then display a menu over the top of the output (by, for example, clicking on the K menu so it covers the konsole), output from tail is not drawn to the screen while the konsole is covered. This leaves gaps in the output which then propagate up the screen as the konsole scrolls (see a screenshot at http://benroe.com/images/konsole.png).

This is using XFree86 4.3.0, Nvidia drivers with backing store enabled. It doesn't happen with xterm. Forcing the konsole to redraw (by resizing the window etc.) fixes the display.

Try without backing store. I doubt that this is Konsole specific, try for 
example KEdit or Kate.
Comment 2 Benjamin Roe 2003-09-28 22:47:49 UTC 
I tested it, and it doesn't happen with backing store disabled.

Hi,

tested it here with current CVS HEAD + Qt3.2 and can't reproduce it.
