[Qt-interest] Problem: X Error: BadWindow (invalid Window parameter) 3 ...

[Zeljko]

Hi,

Sometimes my app hangs with gazillion of messages like this in console
(so I need to kill my app) :

X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 40 (X_TranslateCoords)
  Resource id:  0x380b94c

There's no rule/time how/when to reproduce that, but I think that happens
when switching virtual desktops, and my app is idle.

Using Linux-2.6.26, glibc-2.3.4, qt-4.4.3 (happens with 4.5 snapshots also &
happened with qt-4.3). 
XOrg:
name of display:    :0.0
version number:    11.0
vendor string:    The X.Org Foundation
vendor release number:    60802000
X.Org version: 6.8.2
maximum request size:  16777212 bytes
motion buffer size:  256
bitmap unit, bit order, padding:    32, LSBFirst, 32
image byte order:    LSBFirst
number of supported pixmap formats:    7

Anyone have any idea about this ? What can cause such problem between Qt <->
Xorg ? There's nothing in error logs, it just start to produce above
mentioned X error ....

tnx.
