Adobe Reader is extremely buggy and is therefore not a pleasure to use. Here are a few things that need to be fixed:

When viewing pdf files such as building plans, when zooming in and out, colours change. Light orange will for example become dark orange etc. This applies to vector lines and masked areas. Zooming in and out fixes and makes it incorrect in a continuous cycle. Please fix this.

I often cannot open a file while Acrobat Reader has a file open already. Closing Acrobat Reader and opening both files again then fixes the issue. This happens all the time and this is annoying if you want to be productive.

Adobe Reader also crashes a lot for no apparent reason.

The performance of Acrobat Reader is poor, even with my good hardware. Not sure why my 2D building plans are lagging, when I can smoothly have a massive 3D model in another app with no issues at all.

I am also posting this here, because I cannot find a proper way to report bugs. Please make reporting bugs easier. This probably contributes to why the app is so broken.
