I have created a QTable object on the form and i set the cells with some text.While running the application, the set text becomes darker(than normal) and at this point i get the above mentioned error.I also saw the file /usr/include/X11/Xproto.h which says a major opcode of 59 indicates some (X_SetClipRectangles)what is this???can u pls explain.
Thanx in advance.....

Do you use threads?

Which Qt version do you use?

[wysota]

Could you provide a minimal compilable example reproducing the problem?

[mahiapkum]

3.3.3 version

3.3.3 version

This is quite old version, so if this is a problem with Qt, then it might have been already solved. If you can't test your application with Qt 3.3.8, then try to prepare a minimal compilable example as suggested.
