Did anyone else faced the problem with the displacement of the Z axis while printing? Any idea of what originates the issue and how to solve it?

I have been investigating further. The problem seems to be related with the buffer size. The more complicated and high resolution the model, the more instruction in the gcode, consequently, the buffer of the printer gets full.
I discovered also that in my case the problem happened while I was using the Creality Cloud app to remotely monitor the state of the printing. So far the only solution I have found is to disconnect the printer from the network and so far so good.
I’ve been having this issue randomly occurring throughout prints ever since I updated the firmware a couple weeks ago. I found that something would cause the printer to freak out when it swung over to the right side of the printer, and it would lose its place and print offset from the model from then on. This sounds like a belt tension problem, from everything I’ve read, but as far as I can tell, there isn’t a tension problem.
Because it seemed to happen most often when the printer made longer movements to the right side of the printer, I thought I might try reducing travel speeds to minimize that, as well as slow some of the layers down. None of these changes worked and it still occurred.
While I have yet to figure out an actual fix for it, the thing I found was that once the print starts, if I set it to print at 90% speed or lower, the issue never crops up (I haven’t tested whether trying, say, 99% has the same result because I got tired of wasting filament). I had a print going at 90% speed overnight, printing perfectly as intended, and then within an hour of setting it back to 100% out of curiosity, it glitched out and the layer shift happened.
