Bug ID: 93458
Summary: STATUSBAR: Word and character count don't update after
high-word-count document loads
Product: LibreOffice
Version: 5.0.0.5 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Keywords: regression
Severity: minor
Priority: medium
Component: Writer
Assignee: [email protected]

This bug appears to be related to Bug 93261 - Persistently high background CPU
usage by soffice.bin with high-word-count Writer document.
In LibreOffice Writer 4, the word and character count displayed in the left of
Writer's statusbar would periodically update in real time shortly after a
document was loaded, letting the user know that Writer was (apparently)
repaginating the document and updating its statistics in background. Sometimes
the display update would be paused or interrupted if the user initiated a task
(e.g., switching sidebar panels) before the background repagination/statistics
updating was complete, but the word and character count would generally display
correctly once the task was complete and focus was returned to the document's
main frame.
When a high-word-count document is loaded in LibreOffice Writer 5.0.0.5 for
Windows (both x86 and x64 editions), the word and character count DO NOT update
in real time, and in fact do not appear to update AT ALL until the user has
engaged in some foreground activity in the main document frame, e.g., by
editing, initiating a spell check, jumping to a bookmark, or jumping to the end
of the document. (Significant scrolling seems to trigger a statusbar update but
minor scrolling does not.) The word count and character count typically start
out by immediately jumping to (very roughly) around 1,700 words and 10,000
characters, and they remain at those initial numbers until the user engages in
foreground activity.
Word and character count automatically update within a reasonable time (albeit
in a single jump, without intermediate refreshes) for ~14,000-word and
~70,000-word documents. They NEVER update on their own (without user activity)
for ~430,000-word, ~570,000-word, and ~720,000-word documents. The bug can be
tested on the documents I uploaded for Bug 93261.
This bug, in itself, is only a minor annoyance -- the user doesn't know when
Writer has finished repaginating and updating statistics in background -- but
it's a clear regression with respect to LibreOffice 4. That said, I suspect it
is connected to another bug I noticed in LibreOffice Writer 5.0.0.5 (Bug 93261
- Persistently high background CPU usage by soffice.bin with high-word-count
Writer document). Is it possible the initial background
repagination/statistics-updating routine gets stuck in a loop in
high-word-count documents? If so, manually updating document statistics (File >
Properties > Statistics > Update) doesn't seem to break it.
