Garbage at end of edited line in Writer

When editing text, insertion or deletion often does not correctly refresh the
display until I force a refresh (by scrolling the window, for example), or
until what appears to be a built-in timer initiates a refresh after a number of
seconds, which I have not been able to time. (The only timer I can identify is
in Options/Load Save/General/Save AutoRecovery Information, which is set to 15

Garbage remains on the affected line, to the right of the insertion/deletion
point. Often, the remaining text is truncated so the first character of the
spurious part is only partly displayed.

This bug was posted to Linux Questions and at least one other user, on a
different platform, has noticed the same problem. See

I have also created a LibreOffice bug report at

In Options/LibreOffice/View, I am using Hardware Acceleration and AntiAliasing

  • that is the way LibreOffice was configured at installation time and I have
    not changed anything.

Under Fedora 14, using Compiz, I had identical display refresh errors when
editing an OpenOffice Writer document. The fix then was to edit the Compiz
settings, to enable the module ‘Workarounds’. I cannot find any equivalent
option with my current system.

I do not have display rendering issues with any other application.

Hardware is a Lenovo T61. I am using the proprietary nVidia display driver.

Until that bug is fixed try resolving the problem by turning off Tools → Options → LibreOffice → View → Use hardware acceleration.

Excellent! That seems to work perfectly. Thanks for the tip. I will update the bug report to indicate this workaround.

Current status of fdo#49986 is RESOLVED FIXED.
