High keyboard latency - low CPU usage- when running multiple instances of JTAlert

Hi Folks,
As a Flexradio user and I typically operate WSJT-X with at least 4 bands running simultaneously via my 6700. I will feed each slice of the Flex to a different WSJT-X process, and then I will run an equal number of JTAlert instances, each capturing the UDP stream of the individual WSJT-X process. Being able to monitor every band I'm interested in simultaneously is the primary reason why I chose to buy a Flex radio.
I have noticed that as I add more JTAlert instances, my Keyboard latency will decrease linearly. By the time I have reached 4 processes, the latency is to the point where typing is very difficult. It feels like 500ms or even higher.
My system is not taxed at all with all these programs running, I have a 12-core 4.0Ghz processor, and 32GB ram with a very fast GPU, and NVME storage. CPU usage while decoding 4 bands is 10- 20% & memory consumption is about 50%.
I have tried debugging for most of the day, and can confirm that the latency only happens with multiple JTalert instances running. I do not feel any keyboard sluggishness when I add more WSJT-x or Flexradio slices.
I have opened a discussion on the JTalert support site & at least one other user confirmed the same thing. If you have experienced this problem, please chime in on this thread at hamapps support.
Thanks in advance!

[{"insert":"Thanks to the community for helping to troubleshoot. We can confirm this is a real issue, (specifically with Flexradio users since we run multiple instances) and we did find a work-around. I posted the details in the thread above but you need to go into JTAlert settings, Miscellaneous, Hot Keys, and disable all Hotkeys. \n\nI am currently running 5 instances & am able to type this message at the same time.. It was impossible to do this prior. \n\n73,\nW9PDS\n"}]0
