Blue wave from a default template

The background images of the templates in LibO 6.0 seems to are in low resolution and looks pixelated. Higher resolution images should be included. No blur and "stairs" should be visible in non-vertical or non-horizontal borders/lines.

Tested with version (x64)

Monitor: 1920 x 1200 px, 24"
with NVIDIA Quadro K2200

Such simple kind of decoration as in "Blue Curve" shouldn't be a raster graphic at all but a vector graphic, esp. as it is not the background graphic of the slide, but an image inserted as background object.

Please describe precisely which templates need to be improved.

using a vectorgraphic

The screenshot from Thomas Lendo is from template "Blue Curve". The image on the title slide master has width 1057 pixel and height 185 pixel. But the problem is deeper than exchanging the image. I have tried a vector graphic (see attachment). In edit mode it is fine, but in presentation mode anti-aliasing is missing. The problem is more visible in 4:3 than in 16:9. So using vector graphic (as I first thought), will currently not solve the problem .

All Templates get an update and the master page background are now LibreOffice shapes so there is no resolution issue any more.

Two templates didn't get an update (now) and use the old background cause I was to lazy.
