[Bug]: High GPU usage, low FPS and sluggish IDE feel

[nikiepaydk]

Describe the bug

Hi, Great plugin. Has used it for many years.

I am seeing my IDE become more and more sluggish. And it has gotten to the point where I today had to disable Material Theme UI to restore it to a functional level.

When I disable the plugin, everything is fluent and snappy. I do not have the best GPU in my workstation, but today it was often stuck at 70% usage while the IDE was open and using over 6GB of VRAM for for GoLand. My CPU is plenty powerful.

I am happy to help collect debug diognostic - If you can instruct me how.

To Reproduce

1. Install the plugin
2. (I use palenight theme)
3. Click around, the IDE becomes sluggish

Expected behavior

The IDE to behave fluent and not sluggish

Material Theme Version

v10.9.1

IDE

Other (AppCode, CLion, GoLang...)
