Hi Prashant, Is your application performing a rapid sequence of resizing operations on the EGL window that leaves the size of the window unchanged? We recently discovered that this can cause the QNX Qt platform code to produce this problem. I haven't had a chance to upstream the fix for it yet. We also haven't updated the Qt that QNX produces (which I think is what you're using).
You might be able to get around the problem if you can give the application a chance to draw between resize operations.
