Mouse move CPU load 90%, even with Power mode enabled!
Hi, I believe this affects all intellij softwares..at least I tried with php storm and pycharm.
Moving the mouse around, even with power mode enabled, spikes the cpu to 90% and I have a pretty good pc (4800U).
Older versions (2019) didn't have this obvious issue, my laptop battery is hugely impacted by this.
How can I solve this issue?
I want my ide to just do nothing as I move the mouse around. No cpu should be impacted.
Version Build #PS-213.6777.58, built on January 31, 2022 (but It doesnt matter...does the same with older versions too)
Power safe mode should REALLY save my battery.

I'm currently running win 11

well, after digging online, lowering the polling rate of the mouse can mitigate this issue. I had 1000hz polling rate in my logitech control panel. Lowering it to 125hz I get this:
%CPU Subsystem
20,9 <Process total CPU usage>
14,7 <infrastructure: AWT-Windows>
2,3 <infrastructure: UI thread>
0,7 vfs.newvfs.impl (in com.intellij.openapi)
0,7 <unidentified: UI thread>
0,7 editor.impl.view (in com.intellij.openapi)
0,7 <Activity Monitor>
0,7 application (in com.intellij.openapi)
So this magical "infrastructure: AWT-Windows" passed from 45% CPU to 15%, it's a pretty significant change.
I still think it really should not behave like this (other softwares are not even close to this bad performance shown in Pycharm)..but ok.
Thank you for the update! There was no chance I could figure it out.
