            Bug ID: 114255
           Summary: Keystrokes sent in wrong order under high cpu load
           Product: LibreOffice
           Version: 5.4.1.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: julo42 at gmail.com

Description:
When my computer is under high cpu load, if I type a sentence, I don't see it
appear immediately (the display isn't refreshed as I type). Then, when it
finally appears, the letters are in the wrong order. For example, if I try to
type "Libreoffice rocks", when the text appears it shows "Lbrioeiff ecosrkc".

This bug is 100% reproducible under heavy cpu load, but never happens under
normal cpu load.

Steps to Reproduce:
1.Launch a task that causes high cpu load (for example 'rsync' on my laptop)
2.Switch to LibreOffice Writer and start typing a sentence.
3.The sentence doesn't appear immediately.


Actual Results:  
When the sentence finally appears, its letters are scrambled.

Expected Results:
The sentence whould have its letters in the right order.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes
