Impress Letters smudge during slide show

On running the slide show, the letters lose their sharpness. The edges lose their shape, there is shadowing of letters, or the edges or smudged by the background.

That is probably known issue tdf#107090.

For now, work around is to disable “Use hardware acceleration for all rendering”, or enable “Use OpenGL for all rendering” from the LibreOffice Tools → Options → View panel. Some of the transitions with CPU only rendering will not run.

Thanks will update you soon after changing the settings.

Thanks. Will update you soon.
