Description benico 2019-03-22 23:37:06 UTC
Description:
In LO-Writer "Custom Properties" "Text Fields": touching the "shift-key" (to capitalize letters) pushes CPUs to 100%. 

Fault is not reproduced with Caps Lock nor if the fields are copied & pasted.

Steps to Reproduce:
1.Start Writer and goto File -> Properties -> Custom Properties
2.Create a new Property of type text ... Give it a Name 
3.Start to enter the field value for that property and use shift-key to capitalize a word.

Actual Results:
Properties Box freezes, CPU's go to 100%. It does recover after a while.
With the AppImage version the [OK] [Cancel] [Reset] and [Help] buttons also continue to flicker in a fast sequence one-after-the-other ... after some time (dependent on the number of capitals) the cpu load goes down and the typed letters appear in the input box.

Expected Results:
Just entered a capital letter - without freezing up the system for 30s to 3min.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
This bug is present since release 5 ... installations has been on various computers with Ubuntu 16.04 as well as 18.04. Installation source has always been the zipped .deb packages - with the EN-ZA helppack and the AF and EN-ZA langpacks.

It also does this in safe mode. It almost looks as if it wants to look-up something. It also happens when naming the custom fields.

i can not reproduce it with

Version: 6.1.5.2 (x64)
Build ID: 90f8dcf33c87b3705e78202e3df5142b201bd805
CPU threads: 4; OS: Windows 10.0; UI render: default; 
Locale: de-DE (de_DE); Calc: 

so maybe a Linux only issue
