Extremely slow Replace when changing line count #363

Closed ProgerXP closed 1 year ago

For example, take a document with 2000 lines in C format (line\nline\nline) and Replace from \\n to \n in either Regexp or Transform backslashes mode. This will take up to 10 seconds depending on the document, Word Wrap state and probably other parameters. In Notepad++ this takes half a second at most.

This might be because window state is updated during the replace (I see scrollbars changing).

Related issue: after you convert \\n to line breaks, do Ctrl+Z - it will again take many seconds. In constrast, Ctrl+Shift+Z is instant.

Fixed.

Appears to be even faster than Notepad++ in this particular case.
