Gui thread high cpu usage only in renoise

With the latest beta things seem to get worse then ever
When displaying the gui of certain plugins , the cpu in taskmanger doubles ( purely gui related and not audio related thus not shown in renoise’s cpu meter )
I tested this with other hosts, architect, studio one , reaper …renoise is the only one exhibiting this behaviour ( screeshot shows cpu usage while no actual audio is being processed ) , the vst is audio realsim adm ( demo version )

Please fix this
