Bug ID: 158562
Summary: EDITING: Cursor movement and typing out of sync
preventing work in complex documents
Product: LibreOffice
Version: 7.6.2.1 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
There is a delay of up to 20 seconds between the request to move the text
cursor/caret (pressing Left/Right/Up/Down arrow keys, or Backspace or Delete or
selecting/putting a cursor with mouse pointer) and the change taking place;
because Writer treats the typed characters asynchronously from the
selection/cursor position this leads to the core functionality - writing -
being not usable in the large document.
For the past few months I was writing in gedit and copy-pasting chunks. The
bottleneck is though that if I want to perform any formatting or replace
existing text I need to select things and this takes many seconds/is not
reliable.
Steps to Reproduce:
1. Open a large, complex document (50k+ words, hundreds citations, many
figures, a few footnotes - basicaly a doctoral thesis which I cannot share yet)
2. Type "qwerty"
3. Press left arrow key
4. Type "aaaaa"
Actual Results:
"qwertaaayaa"
Expected Results:
"qwertaaaaay"
Reproducible: Always
User Profile Reset: No
Additional Info:
This appears distinct from issue 133137 because that issue describes problem
with typing alone. For me typing works perfectly (as long as I do not press
backspace or ever make an error which sadly is not that long).
This appears distinct from issue 153828 because switching to SAL_USE_VCLPLUGIN
gen or SAL_USE_VCLPLUGIN kf5 does not fix it.
This appears distinct from issue 148433 because I do not use both RTL and LTR
characters and it affects all paragraphs alike.
This is not caused by the number of words alone - I created a document with
100k words using Lorem Ipsum and the issue was not there.
I tried dissecting the problem by splitting my thesis into smaller chunks (it
was already happening at a single chapter level) but I could not narrow it down
to a single feature (like figures/tables/references) just yet.
This is not a regression in the recent release - it was like this in previous
version (7.5) too. I will try to test older versions soon.
