RetroArch's theme Battery and Clock icons are quite small compared to the image size:
As a result, when using a theme outside of Monochrome that has standard sizes for the icons (like the Material Design theme), the icons end up looking rather large in RA:

RetroArch should render the icons smaller on the frontend, rather then expecting the theme to have battery.png and clock.png render small images.
Themes should be able to use a full-sized version of a clock.png.
I really hope that pic does not say 118% battery

It really does say 118%.... Just ignore it, I'll update my kernel soon.
Yeah, your battery is at 214748364800% and everyone who disagrees is a Microsoft lackey.
The two PRs are now open over at https://github.com/libretro/RetroArch/issues/4616 and https://github.com/libretro/retroarch-assets/issues/122 . @Kivutar mentioned he'd be willing to test.
Going to close this, seems there's some mipmapping issues. That's beyond my knowledge.
