Description nfxjfg 2019-05-11 13:22:34 UTC

2. open a file

OBSERVED RESULT

Don't see a vertical word wrap marker line.

EXPECTED RESULT

Should see a vertical word wrap marker line.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: yes/no
(available in About System)
KDE Plasma Version: uh I don't run KDE, so no clue
KDE Frameworks Version: 5.54.0
Qt Version: 5.11.3

ADDITIONAL INFORMATION

Happens in kate 18.03.70 (what I'm using mainly), 18.08.0 (current Debian unstable version), and 18.12.3 (current Ubuntu version).

It did not happen in 18.03.70 a few weeks or months ago. I did not rebuild kate or any of the other components that are built when using the build instructions on your website. This hints that a change to any of the dependencies might have caused this. I still have a few running kate instances that render the indicator correctly, but their about dialogs show the same Qt and KDE frameworks versions.

Comment 1 Lothar 2019-05-12 20:32:15 UTC

Perhaps not a fixed font in use?

Comment 2 nfxjfg 2019-05-13 15:53:13 UTC

It's a fixed width font. Liberation Mono, Regular, 10.0 points. Hidpi with QT_SCALE_FACTOR=2.

Comment 3 nfxjfg 2019-05-17 15:36:07 UTC

I went and commented the "QFontInfo(config()->font()).fixedPitch()" check in katerenderer.cpp. This makes the marker appear again.

The font I'm using is most definitely fixed width, though. Some kind of font handling regression in some other library? Checking fc-cat and looking for "Liberation Mono", all related entries end with "variable=false".

Anything else I could check?

Comment 4 Ahmad Samir 2019-06-22 13:26:21 UTC

I couldn't reproduce this issue, the static word wrap marker is shown here with Liberation Mono at 10pt. Note that I don't have a HiDPI display.

Comment 5 nfxjfg 2019-06-22 16:55:56 UTC

Still happens to me. This is on Debian unstable. The kate version I tested is also from Debian unstable. What I wrote in my previous post probably still holds true. It must be a change in some of the dependencies. (Qt? fontconfig?)

Comment 6 Christoph Cullmann 2019-07-13 19:02:29 UTC

    show static word wrap marker always if requested
    
    Summary:
    don't check for fixed pitch font, as this seems to be not properly attributed
    to all kind of fonts

Comment 7 nfxjfg 2019-07-16 14:02:22 UTC

Thanks. If anyone knows why this happened or how to analyze it, that would still be interesting.

Comment 8 Ahmad Samir 2019-07-16 15:32:32 UTC

I tested with liberation-fonts 2.00.1, maybe you have a different version?
