What Happens: When running an application in terminal, either as a launcher or simply opening a virtual terminal directly , the screen output randomly freezes and the generating running application freezes. To resume, one must double-click the open terminal window and/or use terminal reset & clear. The problem makes running almost any application with terminal screen output unusable--for example, running a machine learning algorithm. The problem affects both mate-terminal and gnome-terminal. The bug does not affect a simple x-terminal instance. Affected Applications: gnome-terminal mate-terminal but not xterminal. Test Code: The following simple Python3 code demonstrates the issue. import time starttime = time.time() i = 0 while(True): i = i + 1 print("Still working " , i, " " , time.time() - starttime) When running this code in a mate-terminal or gnome-terminal instance, the code displays a simple message along with the time. After a random period, sometimes seconds, sometimes minutes, the bug arises when the terminal instance screen simply freezes. That is, display output just stops in mid-stream. You can resume but only by double-clicking or using reset & clear. The bug affects at least Python and Java applications with output displaying to the terminal. Approximate Number of Tests: Over 50 and narrowed the issue to the terminal instances.
