I was editing a big csv file ( 76K lines) and did a change that modified all lines in my file.
When I wanted to save it, DirtyGutter started to send events like this for every modified lines
11:52:08 [AWT-EventQueue-0] [debug] EditBus: BufferUpdate[what=DIRTY_CHANGED,view=null,source=imei prefix.csv (%USERPROFILE%\Documents\2.110\)]
I saw some changes in the title bar of jEdit, I think it was ProjectViewer that was receiving those events but I'm not sure, jEdit was unresponsive.
After a few minutes I had to kill it.
I think some things should be done in DirtyGutter for this, like sending events for a range instead of a single line.
