Significant Input Lag and Unresponsive Window after minutes of normal gameplay

My emulator runs smoothly for around 2 minutes and then begins to take inputs incredibly slowly, and the drop down menus (files, emulation etc.) are incredibly unresponsive and take several seconds to respond to a mouse click. Fullscreening/Swapping screens with F11 and F10 also take up to a minute, occasionally causing the window to be unresponsive (though they manage to recover after waiting for minutes).

The emulation sometimes recovers from this after several minutes - other times it does not, and requires a restart.

I should also note that the emulator consistently shows a 100% speed, frames running at an acceptable rate and the display working mostly fine, except when the window is unresponsive.

During the 2 minutes prior to this issue happening, the emulator runs perfectly fine.

Here’s some issues I found with your log that might help.

  • Enabling Accurate Multiplication is recomended in certain games. If you are experiencing graphical glitches, try enabling this option.
  • Please enable the Vsync option if you are experiencing screen tearing.
  • You are using open source system files for Mii data. This will appear as your Mii having broken graphics, but will not affect the stability of the game. In order to resolve this, please refer to our guide on dumping system files.

(I should mention that this did not help. I have tried both settings and they have not resolved the issue. Mii data is irrelevant, the game I am playing does not have Miis)

You should enable Hardware Shaders in Emulation>Configuration>Graphics>Advanced Tab.
Though I’m not sure why that would cause a slowdown of the UI itself.
