Reader DC - Bad Quality (Icons, Images, ...)

Hello,

I have installed latest Adobe Reader DC in my test-Environment running on Windows Server 2016 and Citrix XenApp 7.13.

The graphic-quality is bad in Reader. Especially the Icons in the main toolbar look shabby.
Have a look at the screenshot:

I tried some settings like "bAntialiasGraphics", "bAntialiasImages" and so on, but there was no improvement.

I did also open up a few PDFs and noticed, that the Image quality is also bad.

Does anybody have an idea on how to improve this?

Additional I noticed, that Adobe Reader DC uses ist own mouse-cursor-set. (black-cursor, hand, ...)

Is it possible to prevent the Reader to change the cursors?

Thank you!
