Thanks for all the information everyone. We would very much like to solve this. We are unable to reproduce this or find something that could cause this issue though
. For now collecting more information is all we can do unfortunately.
To that end:
Does anyone experience this issue with an amd card or on macos?
A lot of workarounds have been mentioned to solve it (but none really really solve it). Could some of you who experience this issue perhaps find things you can do to get the issue to be worse? Some users already mentioned having the dmx monitor open or not having arena in focus (which may be the same thing?). Do others experience the same behaviour?
Personally i got a feeling that it could be related to the power distribution within these high-end cards. Would it be possible to run a benchmark tool on these machines and see if their output experiences the same issue? Or perhaps run the benchmark simultaneously with arena to see if the issue becomes worse when load is high.
