#140 closed Bug (cantreproduce)

Log window has visual defects when scrolling to last message entry

Reported by: Matthäus Wander Owned by: Thomas Schmid
Priority: Must have Milestone:
Component: CrypWin Keywords:


  • Open Enigma-Analyzer-Sample-01-JGillogly.cte
  • Make sure log window is turned on (do not change size of window)
  • Click on Enigma and select Operation mode "Analyze"
  • Play and watch log output during the next minutes

Expected: Log messages should scroll smoothly while EnigmaAnalyzer is running.

Actual: Sometimes log window seems to hang in a loop trying to scroll to the last entry (when large messages occur). The log messages are unreadable during this effect. After some seconds, when other (shorter) log messages occur, the effect disappears.

This might waste CPU cycles, therefore becoming a serious bug (considering priority as must-have).

Before r1150 there was a workaround in MainWindow.xaml.cs: don't scroll to last entry every time a new log message occurs, but only every second new message. However, this does not solve the problem (occurs less frequently, but occurs).

Seems it has been fixed by coincidence meanwhile.
