When opening a form in Progress Developer Studio for OpenEdge (PDSOE) Visual Designer, nothing appears on the design canvas. The white area where visible controls normally appear and the yellow area for non-visual controls are both visible, but no form or controls are visible in either area:

This is expected behavior. This issue is with Eclipse and not the AVM. 

1. In the Windows 10 Start menu, locate the Progress program group and right-click the Developer Studio shortcut.
2. Select Properties from the context menu.
3. Open the Compatibility tab.
4. Select the "Override high DPI scaling behavior" check box. In the "Scaling performed by:" drop-down list, keep the default setting of "Application" (NOTE: Depending on the Win 10 version this can change):

5. Click OK.
6. Open PDS using the shortcut.
7. Open a form in Visual Designer. It will now display properly.

NOTE:
From 12.1 onwards PDSOE short-cut uses %DLC%\oeide\launchPDSOE.bat file instead of %DLC%\oeide\eclipse\eclipse.exe, so above steps needs to be performed on %DLC%\oeide\eclipse\eclipse.exe
 

This problem may also be experienced by .Net UI frontend clients.
This problem may also be experienced by other frontends which make use of forms.

Depending on Windows Update settings, the Creators update may have been installed automatically. To check whether the Creators update has been installed:

1. Open the Run dialog (Start > Windows System > Run or CTRL-R)
2. Enter "winver"
3. Click OK
4. If Windows 10 Creators Update is installed, the displayed version will be 1703 (OS Build 15063.0) or greater:

6) Right click on Developer studio icon in the Windows explorer view
7) Click properties
8) Click the compatibility tab
9) Click change high DPI settings button
10) Click the checkbox Override high DPI scaling behavior (enable it).
11) Under that there is a Scaling performed by :
12) Leave that at Application
13) Click OK
14) Click OK
15) Restart Developer Studio for OpenEdge. Visual designer should now work correctly.
