QMainWindows and SystemTrayIcon stops responding and see QXcbConnection: XCB Error
-
My GUI project consists of a QMainWIndow and a QSystemTrayIcon.
When resizing a Citrix VDI screen the QMainWindow and QSystemTrayIcon stop responding and the following is seen in the logs:
QXcbConnection: XCB error: 148 (Unknown), sequence: 842, resource id: 0, major code: 140 (Unknown), minor code: 20
A core dump was produced and after the QXcbConnection is seen in the logs and the UI stops responding thereafter.
After looking through Qt code I saw that this is printed in:
QXcbConnection::handleXcbEvents
If you guys have any idea where I could start investigating or more info on which of the GUI components cause the XCB error that would be helpful.

Hi,
Can you give more details about your setup ?
Which version of Qt are you using ?
On which OS/Distribution ? -
@anshah said in QMainWindows and SystemTrayIcon stops responding and see QXcbConnection: XCB Error:
Citrix VDI
Just to be sure I understand, he uses a remote session ?

You can delete the old icon and instanciate a new one to see if things go better.
