Bug 127742

Description:
What it says in the summary.

There is a screenshot here at https://bug-attachments.documentfoundation.org/attachment.cgi?id=154293 that shows the problem in the wild. The first comment will also provide an additional test screenshot that might be helpful along with an example document.

This issue *could* be a duplicate of #116641, but is for Calc (the other bug is for Impress and there seems to be no way of having a bug marked as affecting more than one component). Earliest affected version is as far as we know; could be earlier.

Marking as "Normal" and not "Trivial", because, although it might seem cosmetic to someone who hasn't learned to read the text of the RTL script being used, the only "workaround" for someone who needs to read it is to keep copying and pasting things out of and into a text editor.

Steps to Reproduce:
1. Install LO, for example the latest version
2. Open Calc
3. Type an English word into some cell, hit space, switch keyboard layouts, then type some Arabic characters.

Actual Results:
See screenshot and compare cells A1 (not in editing mode; correct rendering) and A2 (in editing mode, incorrect rendering) as well as the editing bar above the spreadsheet view.

Expected Results:
Cells A1 and A2 should look the same instead.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
Providing the information from the version that testing started with, as supplied by my distribution.

Version: 6.3.1.2
Build ID: 30(Build:2)
CPU threads: 2; OS: Linux 4.9; UI render: default; VCL: gtk3; 
Locale: de-DE (en_GB.utf8); UI-Language: en-GB
Calc: threaded

There is only one Windows (10) machine NOT exhibiting the problem. It has had Version 5.2.5.1 installed since the day of that version's release, so, basically, since forever.

Other versions tested, downloaded from their respective websites, all exhibit the same problem:

- 5.2.5.1 on Solus OS
- 5.2.5.1 on Ubuntu 18.04
- 5.2.5.1 on LinuxMint Sylvia
- 6.0.7 on LinuxMint Sylvia
- 6.2.7 on Solus OS
- 6.2.7 on Windows 10
- 6.3.1 on Windows 10

NOT exhibiting the problem on either Linux or Windows was Apache OpenOffice 4.1.7.

OpenGL was disabled on one Linux machine while it was running 5.2.5.1. Disabling OpenGL did not improve the rendering.
