[3.03a] Lines in window disappear then reappear as they scroll up.
|
Issue:
As text scrolls up my screen, lines sometimes disappear and then re-appear later as later text is received and added to the bottom of the screen. So text appears, starts scrolling up the screen, disappears, then reappears a bit later.
As this is intermittent and dependent on several items being in sync, this took an extremely long time to first find, then make reproducible. I've at long last accomplished both of these items and packaged it up so that this can be reproduced.
Procedure:
| Code: |
1) Start Cmud, hit escape to enter a blank session.
2) Open the settings editor and go to the XML tab of the main window.
3) Copy the xml code below and paste it right before the last line (</window>), so that it creates a 'temp' folder with various items in the folder. Save and close the Settings Editor.
4) For this to be successful the window size needs to be a specific width. Left click the main title bar of the 'untitled' window and drag it so that it is now floating and you can resize the dimensions.
5) Make the height of the window at least 20 lines.
6) To facilitate making it the right width I created an alias called 'prep'. Run 'prep'. It will output a bunch of dashes. Resize the width so that the window is just wide enough to display all the dashes without any of them wrapping around to the next line.
7) Now that the code has been imported and the window is the right size, run 'runme'.
You'll see raw text I had captured now being displayed with '#showprompt' and '#wait 2000' between each of the lines. I inserted the #wait 2000 to account for the fact that text disappears and then reappears so if I executed it all at once it would disappear and reappear before you noticed anything.
Watch the text as it progresses on the screen. While it is scrolling you'll notice that a few of the first lines disappear and then reappear later as the other text is appended to the bottom.

Also, this bug report needs enshrining as the proper way to do it. Full marks for this thread, ReedN ;)

Awesome! I'm gratified that it was able to be reproduced so easily, thanks for testing it.

Excellent report! I really should resurrect the ancient sticky on proper bug reporting and link this topic to it.
Are you vying for my bug reporting crown? I am willing to pass the mantle. My round form doesn't quite have the shoulders for it; and if I use 2 of my eye stalks to hold it then I can't quite see as many bugs. The crown is shiny though, and I quite like it. |

Excellent bug report!
Confirmed and added to bug list.
But this is a *very* odd bug. Since I'm not in the middle of CMUD bug fixes right now, would someone be interested in playing with this example to try and determine what line is actually causing the problem to occur? For example, does it still fail if all of the ATCP embedded stuff is removed? Is there a specific trigger that is causing the problem? (e.g., does the problem still exist when certain triggers are disabled?)
Good job on reproducing the bug in a reliable way...now we just need to try and simplify the example to get it down to the core bug. |

Thanks. I was ecstatic I could get it even that compact and reproducable, although I know it's a far cry from being pinpointed. In the course of debugging this I even wrote a small perl program to convert the copious raw code I saved to compatible #showprompt statements. It's infernally finicky about a whole host of settings, so I'm sure there's a lot more to it.
