MuseScore crash and weird behaviour on deleting 4 staves
The following photos are taken in the exact order of the file names. I first selected a row that I wanted to delete, then deleted it, then tried ctrl-z and the weird stuff started happening. It gets even weirder with the other example for which I didn't provide the first 3 steps because they are so easy. I am running Nightly 2244 on Windows 7 RC 32-bit. Please if you can guys, fix this because it is kind of annoying. MuseScore seems to handle smaller numbers of measures with 4 staves pretty well, but when the numbers grow, it causes this ugly GUI glitch, and, if you try to delete those visual artifacts that are left over, MuseScore will crash, or, a sure way to crash it is to redo after you tried undo with ctrl-z in order to undo the deletion. That will crash MuseScore for sure alongside the following error messages:

The best way to increase the chances of a bug getting fix is to make it really easy to reproduce. I tried deleteing and undoing with my own scores but couldn't reproduce the problem. See if you can create a simple example and attach the actual MuseScore file you are working with. Better yet create a smaller MuseScore file that shows the problem in its simplest form.
sorry man, my mistake was that I had uploaded in the place of screenshot number 3 the same as number two......... picture number 3 was supposed to look something like number 4 but on the same zoom and system........
what's even more crazy is that I have deleted the screenshots from my laptop after I did the thing, and, now even I can't redo the scenario and make the score look weird again...................... this is crazy............
I imported the same midi file on nightly 2244 and tried the same thing but it just won't work..........
Maybe I also did something else before I tried deleting those measures like adding less stretch or something that made it look that weird.........................
Sorry for the clutter but one thing is for sure, the crash DID occur.............
Maybe there was something wrong with the score?
If you are able to reproduce it in the future open a new bug report.
I'll will for sure!
