Text fad in on click to show change in resolution during animation

Text in a textbox that is shown with the "Fade-in" animation does not display as smoothly as expected.  It looks like the text is faded in at a low resolution (perhaps without anti-aliasing), then, at the end, it jumps to a higher resolution.

Steps to reproduce:
Create a couple of textboxes on a slide in Impress.  Add some text to them.  Make the font large (like, 60 points) so it is easy to see.  Select the "Fade In" animation appearance effect (under special).  Set the animation speed to medium, and, to make it easier to observe, for "Start", select "On Click".

Run the animation

What's observed:
Each textbox fades in, then at the end of the animation, the resolution increases.  (This is especially evident with a lower-case "e".)

What's expected:  The whole animation is expected to take place at high resolution.  (That is the case with PowerPoint on my computer.) 

Without "hardware acceleration" turned on, the animation is atrocious, so this could be related to the amount of memory on the graphics card.

This may seem like a minor matter, but import of animations from my PowerPoint file into Impress results in a very jerky presentation.  This bug seems like a reasonable place to start on that problem.

Thank you for your bug report. I can confirm the text during animations is rendered without antialiasing (which is the word you’re looking for, rather than “resolution” ;), so its borders look jaggy. I guess it was done for performance reasons, but it certainly looks wrong.

With LO 5.1.0, the problem appears to be not as obvious.  Still, carefully watching the fade-in, I see the "unantialiased" font fads in, then at the end of the animation the antialiased font appear all at once.
