Qt Creator 4.6.2 hide blank lines in code editor

[Galbarad]

all was fine yesterday, but looks like it was blackout in office, and perhaps QtCreator broke something

@Galbarad

I can open the file without problems here in Windows and Linux.

So it looks indeed like a problem with your Creator settings.

Can you open the file outside your project in Creator and see if that works? (just to make sure the project settings are not guilty).

[Galbarad]

yes, in Notepad++ it looks fine, but in Creator blank lines missed

@Galbarad

I meant start a new Creator, and just open the CPP file there, like I did, without opening the project.

[Galbarad]

no, didn't help(

[Galbarad]

@aha_1980 maybe QtProject from AppData help?
are you QtCreator developer?)

@Galbarad

You can try starting Creator with settingspath c:\temp (just use an empty directory) to get clean settings and try again.

But if that doesn't help, then I'm out if ideas.

are you QtCreator developer?

Only in my spare time :)

[Galbarad]

@aha_1980 nope it doesn't help(
thanks for your time

[Galbarad]

hm blank lines hidden only between methods, in method as usual (until save)

@Galbarad so please move this topic to SOLVED state.

Strange behavior, nevertheless.
