Question

Hello together

I hope someone can help me with this issue.

I got two Lenovo Thinkpad L15 (Type 20U8) with this graphical error:

Windows 10, 20H2 --> Login --> Starting a Session with citrix workspace, open the windows explorer and getting this. sometimes the error is black, but always in windows explorer

I've tried with another user, with a newer and older version of citrix workspace and the gpu driver. I also changed the settings about DPI and monitor resolution, no reaction. No other Thinkpad has this error.

Someone an idea? I have no clue what's going on...

 

Thanks in advance

J

We found the solution.

We just had to edit the following key to diable Hardware acceleration in citrix. Searching the internet shows, that we are not the only company with this problem.

 

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\ICA Client\Graphics Engine]
"HWacceleration"=dword:00000000
