GPU load is high when emulation is idle

[wangsitan]

Describe the bug

The GPU (of my PC) load is about 10% when the game is running, but it's always about 50%~60% when emulator status is idle (emulation is paused or even rom has not been loaded).

I think the higher GPU load when idle is an issue for me.

When I'm dragging the emulator window (move the window position or change the window size), the GPU load is 0.

Expected behavior

When emulation is idle, GPU load should be low.

Steps to reproduce the bug

1. Don't load game rom, or pause the emulation.
2. Check GPU load on PC.

In the Emulation settings, make sure your swap interval is at least 1 or higher:

Thank you for your reply.
The value was 1.
I tried to change it to 2 / 3 / 10 / 0, got same effect.
