After updating today the DFS AIP charts (paid subscription) I noticed that there were bigger files (around 8-14 MB per chart). When opening i.e. EDNX - Oberschleissheim, it seems that these aren't vector graphics anymore but instead pictures, as you can clearly seen on the below picture from the approach chart ( ~ 7,8MB) with all the compression artefacts. Whereas i.e. the arrival chart (~1,8MB) and apporach chart (~0,6MB) from EDDE - Erfurt is still crisp clear vector graphic.

Was this already all the time, that some charts were pictures? Or might this be a bug ad SD during processing? Or is this part of the DFS "Quality Offensive" to even mock more the paying general aviation?
