Fixing Intellj IDEA lag spikes on OpenSUSE KDE Plasma 6

I ran into JBR-6830 . When using Intellij IDEA on KDE Plasma 6 (OpenSUSE Tumbleweed), I was getting random very noticeable lag spikes. The solution was to add -Dwatch.desktop.geometry=false to the Intellij IDEA custom VM options. No more lag spikes!
