System Information
Operating system: macOS 10.15.7
Graphics card: AMD Radeon Pro 5500M 8 Gb / Intel UHD Graphics 630
Chrome: 86.0.4240.75

Blender Version
Broken: 2.90.0 (release)
Broken: 2.90.1 (release)

Short description of error

Enabling both cavity and XRay causes Google Chrome (at least) performance degrade drastically.

Video demo:
screenrec.mp4

Exact steps for others to reproduce the error

Open attached file or:

- Create new empty project
- Add two array modifiers to the default cube: item count 100, factor -1.2 for X and item count 100, factor 1.2 for Y axis
- Add bevel modifier with default settings
- Enable cavity with default settings
- Enable X-Ray with default settings

With Blender maximized (at least on windows) check the GPU usage - (this can be done through the task manager or browsing Google Chrome)

Note that disabling cavity before enabling X-Ray produces different result. In that case Chrome performs as usual.

It is not a Google Chrome issue. Enabling both X-Ray and Cavity gives an abnormal constant 100% GPU load.

I can confirm a high usage of the GPU in the task manager when both Cavity and X-Ray are enabled.
The Blender window needs to be maximized for this.
Here the file I used:
