Demo of the rendering issue.

Using LibO impress, the quality of presentations is poor in LibO 5.3.

This seems to have to do with antialiasing:

1) Lines that should have the same width get very different widths in presentation

2) Lines that should be joined perfectly aligned (were aligned with the align tool) show "steps" and "gaps".

Point 2) was also present in previous versions of LibO, but 1) has significantly worsened in 5.3 beta.

Exporting to PDF and playing the presentation with a PDF reader gives uniform line width and much better alignment, so the same should definitely be possible also running the presentation from impress.

Two attachments detail the issue.

Seen with Linux and intel graphics.
