I'm trying to deliver an application called NextGen to Windows 11 workstations using an RDP file that shows up as a shortcut with a custom icon on users' desktops. I've managed to get TWAIN redirection working with a third-party app and have the Midmark mostly functional with IQPath for RDP, but it's not completely reliable.
The scaling is a huge headache. I've tried adjusting the ignore scaling registry key on the servers and configured the main EXE properties to ignore DPI settings. Despite these efforts, I'm still experiencing horizontal text tearing in some areas of the interface and truncation issues, especially with column headers. Oddly enough, some workstations handle this just fine.
Has anyone faced similar challenges? Is there a simple solution that I might have overlooked or some specific search terms I could use to find the right fix? This problem is really frustrating me and making me doubt my skills after having dealt with smoother projects for a while.

Have you tried using the Prefer External Manifest registry key trick? That can sometimes help with scaling problems!
It sounds like you're dealing with some frustrating client-side issues here. Make sure to compare the DPI settings, resolution, and screen count between the workstations that are working fine and those that aren't. That might help isolate the problem.
You might have covered this already, but I had a scaling issue with a different app delivered via RemoteApp. To fix it, I set the zoom on the host display to about 125% or 150%, opened a full RDP session, right-clicked on the app, and adjusted the DPI settings there. It worked well for us!
Rendering issues can really throw a wrench in things. I had similar challenges with NextGen and found that updating the server's graphics drivers did the trick.
I've had similar issues, especially with workstations using USB video adapters. Replacing those seemed to resolve a lot of the problems for us.
