In my deployment content is always showing, doesn't matter if scrolling by wheel or scroll bar. -> Office 2019 on Windows 10 VDI

I have the same problem few months ago. It is caused by visual effects. The value is forced by Citrix. You can change this with 1. Set the next key in your image of XenApp, reboot and seal the image. ·HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix Name: EnableVisualEffect Type: REG_DWORD Value: 1 2. Make a User GPO with the next settings: HKEY_CURRENT_USER\Control\Desktop Name: UserPreferenceMask Type: REG_BINARY Value: 9812038010000000 And now I can drag en scroll within my Office application.

Thank you very much @Julien Destombes, works flawless!
