Created attachment 145217 [details] Degraded map Note how the "Paris" label is not degraded
Created attachment 145218 [details] Normal quality map Note how the "Paris" label is now perfectly readable

This is not a bug, but a feature (and the older Marble versions defaulted for LowQuality for performance reasons): Go to "Settings" -> "Configure Marble ..." and on the "View" tab change the "Map Quality" inside the "During animations" ComboBox to "High Quality".
Actually "LowQuality" seems to be still the default during animations in the current Marble master. I will likely change this to "NormalQuality" for the next release.
Great! Thanks for the info, and for the new default setting!
