warning message working with graphics on ubuntu

Asked by Wojciech Guzinski

I have oracle VM 6.1
On this machine ubuntu 19.10
Working with gnu c++ and graphics
At the end of program execution the following message is issued:

[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
xxx: ../../src/xcb_io.c:260: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.

Everything was working fine, just this message....

Any suggestions?

Wojtek

The graphics library that you are using is obsolete and seems to have errors that nobody has corrected so far and which probably will not be corrected any more.

Do you know any other graphics library for gnu c++ ?
