Padshop 2 lags

Hello, I have a question about the Padshop 2 plugin when displayed in the standard plugin version. When I move the window across the screen, a lot of lagging is visible. When I enter the effects or arpegiattor in the plugin, nothing lags. What could this be caused by ? I should add that other plug-ins do not lag when I move the plug-in windows across the screen.

I already know where the problem is. After loading a preset in which the LFO1 Phase is used - the little blinking dot on the right at the bottom of the plug-in, when this is active and I move the plug-in window across the screen - there are lags. When I turn this option off - turning it to zero or to the maximum value with the RATE knob, nothing lags and it is fine. Strange but true…
