            Bug ID: 140217
           Summary: [SLIDESHOW] SVG as background image is rendered in low
                    resolution when in slideshow mode
           Product: LibreOffice
           Version: 6.4.7.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: zigazou at protonmail.com

Description:
If you use an SVG image as background (whether in a slide or a master slide),
the SVG is rendered at the current resolution in editing mode but in a lower
resolution in slideshow thus blurring it.

This is especially visible when using 4K screens.

Any other SVG not added as background image is rendered correctly in slideshow.

Steps to Reproduce:
1. Create a new SVG called background.svg
2. Create a new presentation
3. Set background.svg as the background image of either slide or master slide
4. Run slideshow in full screen

Actual Results:
The background is blurred because it is not rendered at the screen resolution.

Expected Results:
The background should be rendered at the screen resolution.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
