Mouse stuttering / gfx lag in 10.13.2

[funkyfrank]

After the update from 10.12.6 to 10.13.2, I have weird mouse stutters sometimes, esp. if heavy graphics is built-up (e.g. tab switch in safari). Really strange.

I found out that some 2014 mac models seem to be affected (I also use iMac14,2, so similar smbios), too, according to the discussion linked below. This problem is very easy visible if you open anything with uses the JAVA components. E.G. the JAVA system settings (appearing extra panel). Then the mouse will obviously start to stutter.

Found similar reports:

But this stutter also sometimes happen for example if you have many Safari tabs opened, and then close one containing lot of content. The mouse pointer will freeze for some milliseconds then, too!

Steps to reproduce:
1. Use 10.13.2
2. Go to system prefs -> Java
3. Go to tab "extended"
4. Scroll the scrollbar

Or just open any JAVA based app, e.g. Jetbrains Dev tools, Eclipse etc.
