Unstable fps display with touch screens?

[Fielder 3,681]

I  have used Riva Tuner or MSI Afterburner fps displays in MSFS, and they did  work well. But now I set up another small touchscreen monitor to display pop out glass screens (right ALT + left mouse). Either of the two above fps displays will instantly reduce fps severely and cause horrible stutters as soon as I pop out a window (like the GPS 1000). If I turn off the gps display, then no stutters and no fps drop. And if I don't have the touchscreen window on, then all types of fps displays work fine.

Does anybody know of a fps display app that will work with pop out MSFS windows? The Dev Mode fps display works perfectly, but it is very large and in the way.

Frame generation on by chance? Any focus lost will half the frames instantly.

Try using MSFS Pop Out Manager. That might help.  https://flightsim.to/file/35759/msfs-pop-out-panel-manager
