TestComplete is not taking control of the application

Hello Friends,

I am facing a weird problem, we have already developed a BDD Test Suite in TestComplete to Automate Standalone windows desktop application (UI has been built using OpenGL technology), and It's working fine.

We have below Observations/Issues:

1) Test Suite has developed in Windows 10 Laptop with AUT simulator installed in Laptop [Works Fine]

2) Test Suite we ran on Target machine which is real machine via Remote Desktop Connection [Works Fine] 

3) We directly tried to run Test Suite on a real machine by TestComplete or TestExecute which is a Windows 10 machine with Nvdia graphics card [Its Failing]

Reason:

We see that when I execute the test case and once AUT (Windows standalone application gets launches) Test Execution status bar kind of goes to background completely and our AUT will run on foreground, and at the end test case will fail when we see errors it is not able to read the AUT UI because it went behind UI.

The same scenario if I execute via Remote Desktop on Remote computer Test case is getting passed.  

We have encountered this weird situation.

Please provide your suggestions how can we fix this issue.

Thanks
