Description Robert Großkopf 2015-05-01 08:02:28 UTC
Created attachment 115232 [details]
Drwa-example. Click with mouse in the character-field. Then click outside. Some characters are lost.

When editing a Draw-document with text, which is set to a fontsize bigger than 96pt, sometimes parts of the fonts disappear in the design-view.
Text is always visible in the preview-pages.

Could be it is hard to reproduce:
Open the attached Draw-document.
Set zoom to 80%. (seems to be a combination between zoom and fontsize ...)
Click with the mouse in the text of the design-window.
Click beneath the text.
Some characters are gone.

What I could see here is documented with the screenshot.
Seems it doesn't happen with fonts up to 96pt, which could be choosen in the font-menue.

I get this buggy behavior (not every time) with LO 4.3.7.2 on OpenSUSE 13.2 64bit rpm Linux / KDE. Graphics output is set to "Use hardware acceleration" and "Use anti-aliasing". Have also set "Use hardware acceleration" to "no" - same effect.
Get the same behavior with Version: 5.0.0.0.alpha1+, when I try to change the fontsice, for example, to 200pt. All characters were lost ...

Following these steps I can't reproduce with LO 4.0.5.2 and all earlier versions of LO. But it could be reproduced every time here with LO 4.1.6.2 and all newer versions on OpenSUSE 42.1, 64bit rpm Linux, KDE- and also xfce-desktop.

I will set this one as "regression".

Can this be reproduced with >= 5.1.5. I think I might have seen this behaviour before and it was solved by the workaround used to fix bug #99446.
Comment 5 Robert Großkopf 2016-08-03 14:07:13 UTC
Have tested it again with the attachment. Opened the attachment, write in the word "test" "texst". When Setting the cursor an writing a character has been gone in LO 5.0.0 and LO 5.1.0.3.
This doesn't happen with LO 5.1.1.3 and LO 5.0.5.2.

All tested with OpenSUSE 42.1 Leap 64bit rpm Linux.

Can't say why, but it seems the bug has been gone. So I set this to RESOLVED and WORKSFORME.
