after every reboot, the position of xpad window changes, moving higher

[Muhammet Suiçmezs]

After every reboot, the position of the window changes, moving higher a few pixels every time. I haven't paid attention to it for a week and it was off the screen. I had to end the process and whatnot to finally get a new one. The previous one was lost in the process. Even if I could save it, it's a very annoying problem because you need to enable window decorations, put it where you want every time, and disable window decorations.

I have two monitors, one is 1920x1080 and the other is 1600x900. Xpad sits on the latter. Window decorations are disabled.

OS is Ubuntu 20.04.1. It's worth noting that it was also a problem in Ubuntu 18.04, before I upgraded.

I suspect it moves higher as much as the window decoration's length.

I am fine with workarounds if there are any.
