    Hello,

    Using the free version NoMachine Server 6.9.2.1 on a remote headless server and occuring a lot of cpu usage when scrolling with firefox-esr.

    It creates its own virtual frame buffer on xfce so I think it’s the virtual display.

    headless server:  debian buster 10.2, xfce4.12

    The client local: windows 10

    Resolution 1280×1024, quality is on medium. Using H.264 software encoder

    The CPU usage on the client is good but the headless server is over 130% (nxcodec.bin) and nxnode (90%). I can decrease a bit by disabling multi-pass display encoding. Tried to reinstall both but without any good result. When i am connected to NoMachine on being idle: it’s fine.

    Here some files

    I have to say the processus Web Content take between 70-100% cpu, no extension enabled.

    And I am not using the virtual display but the default option: physical display
