[texworks] Texworks 2015 Windows auto spellcheck underline not working

[Beuthe, Tatjana]

Greetings,

As requested, I tested several frequently-used fonts.

The results are as follows:
Does not display red underlining in fonts of 13 pt or above:
Fixedsys, MS Shell Dlg 2, Arial, Helvetica, Liberation sans, Trebuchet

Does not display red underlining in fonts of 19 pt or above:  
Times New Roman.

Does not display red underlining in fonts of 22 pt or above:
Courier New

Does this help?

Hi,

thanks for testing.

Interesting. From browsing the Qt bug tracker and some own
experimentation, it seems that the positioning of the underline is
font-dependent; if it ends up too low, it is clipped.
So: can you try different fonts (from Format > Font...) and check if
some of them show the underline?

In other words, the texts starts out black for a few seconds before turning colorful. This appears to have been fixed in the portable version, but that may also be because the portable version is smaller and takes less time to load, so I don't know if it's really fixed or not.

Yes, this is/was an issue with Qt's layout algorithm; it could happen
that the normal text layout and the syntax highlighting interfered when
run concurrently, producing "invisible" lines that could crash Tw. Work
on this is still ongoing.
