Got the following Blue Screen of Death (BSOD) on my Citrix XenApp 6.5 server.
The problem looks to be with the Citrix Graphics Driver – vdtw30.dll
Patched the Citrix Xen-App hosts with the latest Hotfix Rollup Pack which was Pack 7.

Then applied the following hotfix (KB2748302) from Microsoft which specifically resolves the above BSOD:
