Bug ID: 89204
Summary: VIEWING: Poor rendering performance for images in
Writer
Product: LibreOffice
Version: 4.4.0.3 release
Hardware: Other
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: de...@aiken.cz
Writer has poor rendering performance for larger images in documents. It
appears especially when moving the viewport down/up (scrolling down/up) and
more than a half of an image is displayed (if the images is largely hidden the
rendering suddenly speeds up). The more images are displayed the slower the
rendering is. The scrolling is "choppy" and the displayed images flicker.
Steps to reproduce:
1) Start Writer (a new document is created).
2) Insert a larger image (e.g. using Insert -> Image...); it should be larger
than ca. 1000 x 500 pixels for significant results.
3) Move the vieport vertical scrollbar to scroll the document.
Expected result:
The scrolling proceeds smoothly and the rendered image doesn't flicker.
Current result:
The scrolling is choppy and the rendered image flickers.
Note:
Graphics Output settings are left in the default state.
