Hi,
I created an account on your forum only to add this information regarding this issue that I experimented 40h/week for the past ±12 weeks as I was forced to work remotely (thanks to covid-19).
I would have added the info directly in https://forums.nomachine.com/topic/client-intense-flickering-problem#post-22617 but the thread is locked.
The proposed solution in the last post only works if the NoMachine server has the parameter “Use acceleration for display processing” checked.
This might seem obvious to many, but I though I should share the info as I figured this out only today, after staring at monitors that flickers like stroboscope all day long for the past 3 months…
