Comment 4 for bug 1610601

Confirmed. I'm unable to maximize windows on secondary, bigger monitor and the dragging of windows on the secondary monitor is buggy in this mode (windows snaps to some strange invisible lines)

It's interesting that at the same time if the above, bigger monitor is selected as primary one - everything works as expected. And if the smaller monitor is above of bigger one and is primary - everything works too.

A record of mentioned behavior. The bigger screen is above, the smaller one is primary: https://youtu.be/AWTyEdotPVc.

Screen configuration and xrandr info are attached too
