Unable to capture screenshots/validate bitmaps with Citrix Workspace 2507

[karthikkn24]

Our IT team updated Citrix to a recent WorkSpace 2507 and we are seeing that the screenshots captured via the test tool shows only black screen, it recognizes the window names and it can send key strokes but anything with bitmaps/screenshots are having issues.

We are currently having issue with the LoadRunner tests capturing screenshots or validating bitmaps.

Has anyone tried with the new Citrix Workspace 2507 in LoadRunner and/or JMeter?

Hi,
I had the same issue and found a workaround (source):

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\GfxRender" /v UseD3D11 /t REG_DWORD /d 0 /f

After rebooting, screenshots can be captured normally :)

I haven't had the chance to test the newer versions of Citrix. But generally, in both older and newer versions, the problem was that Citrix didn't support having more than one active video driver on the client machine. The documentation includes a documented workaround.

Perhaps the case of version 2507 is different, and @mhlfst workaround works.
Thanks @mhlfst for sharing,

By the way, we are operating on virtual machines without dedicated graphics hardware (virtual devices only). I don't know if that matters.
We have upgraded to version 2507 because 2402 was causing sporadic heap corruption in ntdll.dll, leading to java.exe crashes.
