Bug ID: 121317
Summary: Libreoffice Viewer on Android breaks with lengthier
files (not just slow but parts missing/appearing after
minutes/excessive render errors/...)
Product: LibreOffice
Version: unspecified
Hardware: All
OS: Android
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Android Viewer
Assignee: [email protected]
Reporter: [email protected]
Description:
Libreoffice Viewer on Android breaks with lengthier files. I tried to open a
DOCX that is long with about 400 pages, but otherwise quite simple (not a large
file, barely any images, simple layout, ...). This file not only loads up in
the desktop version on slower computers without issues, but editing is almost
snappy, even at the top of file where lots of things need to be possibly moved
down when you insert/type.
However, on LibreOffice, not only do I look at a white screen for many
minutes(!), afterwards, a few rectangles of the first page will pop in, some
pixelated, some missing, some swapped, some reverting to black - it looks like
a huge mess, and once I scroll down to page two, nothing again.
Scrolling is smooth, just the contents are affected.
Is there some fundamental design issue going on with everything loaded up into
one unified scrollable texture or something? (Bad idea even on a desktop GPU
for a 400 page document...) Whatever it is, it'd be nice if this could be
changed since this makes the viewer useless for non-trivial document lengths.
Steps to Reproduce:
1. Open a lengthier document (300 pages minimum)
2. Scroll down expecting to see contents & text
Actual Results:
Scrolling is smooth, but I either see a white nothingness, black weird
rectangles, super pixelated unreadable parts or just a swapped out mess.
Expected Results:
I can see the document properly
Reproducible: Always
User Profile Reset: No
Additional Info:
Affected release is 5.2.3.1/01ec8f3 from f-droid, which wasn't listed in the
Versions box.
