Firmware 3.4.0 FSensor Message and printer pauses

I upgraded my Prusa MK3 to firmware 3.4.0 and now I'm getting an occasional message in octoprint and while it happens the printer pauses. I've not seen this before the 3.4.0 upgrade.

It appears to happen when the printer is doing repeated short infill movements (about 3-5 mm strokes)

From Octoprint:

I'm also having issues after 3.4 upgrade, pauses... filament sensor messages, and even nozzle crash into the print 🙁

So far, one print worked (still printing other), with no physical print issues... just the pausing.

Same here. I now have to run with filament sensor disabled. I never had any problems with it before 3.4.0.

RE: Firmware 3.4.0 FSensor Message and printer pauses

was this issue fixed in recent firmwares? I am still back on 3.5.0 and just had this issue for the first time ever and i've printed a lot of small stuff before. had to disable the sensor so it would print proper.
