Just scrolling on a PHP file

Same issue when scrolling in a Java page, with the same stacktrace.
It only happened after some time modifying the file.
Restarting Netbeans is a workaround.

Maybe Editor guys will know where this issue belongs to?

Comment 5 Miloslav Metelka 2015-08-25 13:47:05 UTC

This should already be fixed by issue 213268.
