[Qt5 build] Find tool breaks editor in document with long line and enabled word-wrap

[pintassilgo]

Tested with factory reset CudaText (all default).

https://gist.githubusercontent.com/pintassilgo/9704632c3ce21e4ee9d68918ddd57da0/raw/gistfile1.txt

1. Save this file and open it with with Cuda.
2. Enable word wrap (menu bar > View > check "Toggle word-wrap").
3. Open Find tool with Ctrl+F, then enable "Wrapped search" ('O' button or use the hotkey Ctrl+Alt+N).
4. Type "cached".
5. Press F3 a few times to jump to next match

Suddenly, editor will become blank. There are 7 matches for "cached", the ones causing the bug are the last three. Apparently, some bug is causing Cuda to create a strange horizontal scrollbar that shouldn't exist (because word-wrap is enabled).

In second 6 of the recorded video, I clicked View in menubar and enabled word-wrap, but the recorded video can't show it.

You can see that when editor becomes blank a strange horizontal scrollbar appears. There shouldn't exist horizontal scrollbar in word-wrap mode. The editor is blank because document content is to the left of current position in this strange horizontal scrollbar.

Hm, I renamed the folder 'settings' but I cannot repro this (last 3 matches show OK with word-wrap). @veksha @Vivalzar Do you have repro with clean settings?

[veksha]

can't reproduce too

[pintassilgo]

Maybe it's a bug in the qt5 build. I just tested with the gtk2 and I can't reproduce with it.

[Alexey-T]

yes, I see it now in qt5 build.

[pintassilgo]

qt5 build is problematic, #4955 is similar: gtk2 is not affected, but qt5 is.

[Alexey-T]

found the reason.
on qt5, WrapInfo calculation had a bug.
I did in console:

f=open('text','w')
l=ed.get_wrapinfo()
for i in l: f.write(str(i)+'\n')

and found bad item in wrapinfo. fixing. Thanks!

problematic line in Console-made logfile was:

left file - is bad. 'final':0 was bug.
