We were previously running Libre Office 6.1.4 on Windows Server2008R2 without problems.
When we virtualized the 2008R2 server on Hyper-V (Server 2016std) LO got really slow.
Opening menus is almost impossible and typing text on e.g. a Calc chart takes very long, typically 3sek delay.
The strange thing is that it is only LO which is affected.
We have reinstalled LO and have tried with both x86 and x64 version. An older LO version 5.4.4 was also tested with the same result. Antivirus was also reinstalled and temporarily disabled during the tests.
Now we are running OpenOffice 4.1.6 x86 and that works fine.
On most forums it is suggested to change settings in LibreOffice for OpenGL and hardware acceleration but that does not help.
Have anybody else experienced similar problems after virtualizing?
What components, services or other is Libre Office depending on that could cause the extremely slow user interface?
