I can reproduce this with the attached test. The problem appears to be that when Qt Creator reads from the pipe, it assumes that whatever it read is a full line after a time out, when it isn't. It doesn't update the previous line when more characters are received. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering
