Description Persso 2020-01-29 22:25:32 UTC 
SUMMARY
I'm using two monitors on KDE neon 5.17, with an nivida(1650) gpu. Both monitors are connected to this gpu.

I'm using kde connect from the playstore on my pocophone with android 10. I'm, using the external input feature.

When scaling is turned up, the cursor flies from my main monitor to the far side of the other monitor when moving the cursor to the second screen with kde connect. When I turn off scaling, eg using the default scale, this doesn't happen, it only happens when scaling is turned on/increased. So the bug seems to have something to do with scaling. My second monitor also has underscan set to 38 in Nvidia-settings. 

STEPS TO REPRODUCE
1. Turn up scaling via KDE settings 
2. Move cursor with kde connect to second monitor
3. It will fly to the far side of the monitor and stay there.

Not sure if related but when I have scaling turned up I have similar weird issues.

When moving my mouse to the right hand corners of my screen (particularly difficult when attempting to scroll), it will leap towards the left into the center of the screen slightly, and when doing it on the left hand side of the screen it is even weirder, and it will glide upwards towards the top of the screen (the more I slide my finger left on my phone the more it glides up as if the axis were changed)

I have the same problem on Linux Mint 22.1 with Cinnamon DE and Muffin window manager (x11)
