Check spelling pop up window displays garbled text in "unknown word" field

[KarlMagnusLarsson]

Environment

• TeXstudio: 2.12.10 (git 2.12.10-73-g0ba02d02), latest git repo source as of 13 aug 2018.

• Qt: Using Qt Version 5.11.1, compiled with Qt 5.11.1 R.

• OS: OSX 10.13.6 uname -a.
  Darwin Magnus-Larssons-iMac.local 17.7.0 Darwin Kernel Version 17.7.0: Thu Jun 21 22:53:14 PDT 2018; root:xnu-4570.71.2~1/RELEASE_X86_64 x86_64.

• TeX distribution: MacTeX-2018 (Texlive)

Expected behavior

Tools->Check Spelling pop up window displays current word in "unknown word" field. If "ignore" button is pressed, the next word to be checked is displayed.

Actual behavior

The "Unknown word" field in "check spelling" is garbled. It looks like only the upper half of the field is updated with the new word. The lower half of the filed remains as before, i.e., the old word is displayed. The result is a cut up of two words. Please refer to the example picture attached.

How to reproduce

1. Open Latex source file.
2. Tools->Check Spelling.
3. Jump to next word to be checked by pressing "ignore".
4. Repeat 3) a few times

Notes:

• I have compiled from source as per mac instruction in Wiki https://github.com/texstudio-org/texstudio/wiki/Compiling.
• I have updated Homebrew: brew update, brew upgrade.
• OSX is updated.
• I will have to do some more tests, so this is not a fact and I can not yet prove it, but it seems that this issue persists even if I check out older Texstudio source, i.e., 2.12.8 and so on. If this is true then the resolution is related to something outside the Texstudio source.
• Am I the only one who sees this on Texstudio OSX?

I did some more tests.

The garbled text is only displayed if there are two or more, different, "unknown word" on the same source text line in the editor window and you step between the "unknown word" using ignore.

If pressing ignore moves "unknown word" to a new source text line in the editor window, then the Check Spelling window is fine and no garbled text is shown.

Can anyone reproduce this on OSX Texstudio, or am I the only one with this error?

Works for me. Problem does not appear when I rebuild Texstudio.

I am using an old mid 2010 iMac, with OSX 10.13.6, but I now have 10.14 of the platform SDK. I get a warning due to this when I build, but Texstudio works fine.

I also noticed that "brew update", "brew upgrade" pulled a new qt-5.11.2.high_sierra.bottle.tar.gz and new poppler --with-qt: https://poppler.freedesktop.org/poppler-0.69.0.tar.xz. However I do not know where the crucial change happened.

Build warning as per below with statement about SDK 10.14.

$ qmake texstudio.pro
Project MESSAGE: Building with Qt5

Project WARNING: E.g., 10.14 enables dark mode and layer-backed views, which Qt 5.11 does not support.

Works for me. Problem was related to dependencies outside of Texstudio code.
