Test file

I have a simple sample (created with 5.4.4) with a text box and only one word in it. This is cut off somewhere in the middle. The rest of the text is invisible and only shows partly when selecting and holding the text box. This happens with 6.1.3RC1. With 5.4.4 everything looks fine.
Comment 1 Gerhard Schaber 2018-10-31 13:53:07 UTC 
I am using Windows 10, build 17134, 16GB RAM.

Tests with that file:
LO 4.5.4: ok
LO 5.4.4: ok
LO 6.0.6: ok
LO 6.1.2: ok
LO 6.1.3RC1: not ok
LO 6.1.3RC2: not ok

It seem it always makes a different piece of the text invisible when opening the file.

Could you please add a screenshot of the right and wrong behaviour?

OTOH, Does it work if you disable OpenGl ? -> https://wiki.documentfoundation.org/OpenGL

I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the issue is still present

Comment 6 Gerhard Schaber 2018-10-31 15:22:41 UTC 
You are right, this depends on whether OpenGL rendering is on or not.
Comment 7 Aron Budea 2018-11-01 07:00:43 UTC 
Confirmed with LO 6.1.3.2.

Version: 6.1.3.2 (x64)
Build ID: 86daf60bf00efa86ad547e59e09d6bb77c699acb
CPU threads: 16; OS: Windows 6.1; UI render: GL; 
Locale: hu-HU (hu_HU); Calc: CL

No issue with a recent master build, now the question is, which backport has caused this issue, and what could be missing?

Version: 6.2.0.0.alpha1+ (x64)
Build ID: 140434a7677946020bb2c6db9ed3afe8998ee7d0
CPU threads: 16; OS: Windows 6.1; UI render: GL; VCL: win;

Comment 8 Aron Budea 2018-11-01 08:47:57 UTC 
Fixed in bibisect-win32-6.1. Reverse bibisected to the following fixing commit, which is in libreoffice-6-1, but did not get in libreoffice-6-1-3. Not setting this bug as duplicate of bug 120204, since the two issues appeared independently.
