Description Eyal Rozenberg 2023-09-30 19:30:32 UTC
Consider the attached document.

If you continue typing Hebrew at the end of the paragraph numbered (1.), after the word מספר and the space - but you type quickly, just type gibberish and spaces - at some point while typing on the _next_ line, the text starting from the beginning of the next line to half-way to where you're typing will become boldface; but don't stop typing when this happens - continue typing gibberish and spaces; the text will then _lose_ the boldface. And this change will repeat itself more than once as you're typing.

This may or may not be related to how the document was originally a larger document imported from an MS Word .docx file.

Also, I have not seen this behavior when typing gibberish in English instead of Hebrew.

Document for reproducing the bug

I should also mention that if we clear all DF, the entire (1.) paragraph becomes boldface'd. However - I have not un-boldfaced it using DF while editing. I had only ever double-clicked the "No Character Style" item in the styles sidebar.

Thanks Eyal.

I could not reproduce with:

Do you have the David font installed or is it using a fallback?

And noting that the paragraph uses the "Emphasis" character style, which has the bold font effect.

Both... I'm using a fallback to David CLM, but I also have it installed.

Comment 5 Stéphane Guillou (stragu) 2023-10-17 15:04:52 UTC
I can't reproduce, even with David installed.
Any chance you can attach a video of the issue?
And can you reproduce in previous versions?

Screencast of the effect of continued typing

Note that in this screencast:

* The only actions performed are initial cursor placement with the mouse, then typing Hebrew characters and spaces. No other action is taken, no shortcut keys etc.
* If one types English instead of Hebrew, this does not happen.
* The David font is substituted for David CLM. Both fonts are installed on my system, with versions 5.03 and 0.120 respectively.

Comment 7 Eyal Rozenberg 2023-10-19 09:05:15 UTC
Ok, narrowing down the reproduction instructions: In the attached document, just ype ע once. That triggers the emboldening. As you type ע and space, repeatedly, filling more lines, you will the emboldening on the first line gone, then see it appear as you are typing in more of the second line, etc.

I'm also able to reproduce with:

No problem for me with spaces and (pasting) ע into the example document.
