Hello, I'm Maneshwar. I'm building git-lrc, a Micro AI code reviewer that runs on every commit. It is free and source-available on Github. Star git-lrc to help devs discover the project. Do give it a try and share your feedback.

I boot up my machine. The desktop loads.

And before I open my editor, before I check Slack, before I do a single productive thing, I right-click an empty patch of desktop and hit Refresh.

Then I do it again.

And again.

I am a person who can explain event loops and reason about cache invalidation, and yet here I am, mashing F5 on a static wallpaper like it owes me money.

If you've never done this, congratulations, you're better than me.

If you have... welcome.

You're among friends.

First, let's kill the myth

There's a folk belief that refreshing the desktop is a tiny act of system maintenance.

A little spring cleaning.

A gift to your hardworking CPU.

It is not. Manually refreshing your desktop does not:

free up RAM
reduce CPU load
clear some mysterious cache
make your PC faster in any way, shape, or form

All it does is tell Windows Explorer to redraw the current view.

That's it.

That's the whole feature.

What's actually happening under the hood

Here's the part that's actually interesting (we're devs, we live for the "actually").

Windows doesn't repaint your entire screen on every frame, that would be wildly wasteful.

Instead it leans on a composition engine that, with help from your GPU when one's available, only redraws the regions that changed since the last frame.

Already drawn elements get cached and reused.

Icons, the taskbar, your wallpaper they're all mostly static, so mostly left alone.

When something genuinely changes (you save a file, delete a folder, plug in a drive), the OS detects it and tells the composition engine: "hey, this little rectangle changed, repaint just that."

The desktop refreshes itself, automatically, all day long, without you ever touching anything.

So the manual Refresh button is really just a manual override for the rare moments the automatic system hiccups:

you deleted a folder but its ghost is still sitting there
an icon that should exist is missing
the sort order looks scrambled

In those cases? Refresh away.

It genuinely fixes things.

The other 99% of the time, you're asking a system that already updated itself to update itself again.

The plot twist nobody wants

Since the OS already handles all of this automatically, an unnecessary refresh doesn't relieve your computer of anything.

It gives it extra work.

It's microscopic, we're talking a rounding error of a rounding error, nothing you'll ever feel.

But it's still deliciously ironic: the people refreshing to "help" their PC are, technically, the only ones giving it pointless homework xD

So why can't we stop?

This is the good part. It's not really about computers at all.

It's the same wiring behind crosswalk button syndrome, jabbing the walk button five times because surely that makes the light change faster. (It doesn't. Many of those buttons are on fixed timers, and a surprising number are straight-up placebos left in place because removing them costs money.)

Or elevator button syndrome, pressing the already-lit close button as if your impatience is being measured and rewarded.

The refresh button gets a bonus boost, though: it's literally labeled with a word that means renew, restore, freshen up.

The UI is basically whispering

Of course we believe it.

The verdict

Refreshing your desktop is a placebo with a side of busywork.

It costs you nothing, helps you nothing, and let's be honest it's not going anywhere.

Knowing exactly how the composition engine works will not stop me from right-clicking → Refresh tomorrow morning.

Some rituals aren't about the outcome.

They're about the click.

Now if you'll excuse me, I have a desktop to refresh xD

AI agents write code fast. They also silently remove logic, change behavior, and introduce bugs — without telling you. You often find out in production.

git-lrc fixes this. It hooks into git commit and reviews every diff before it lands. 60-second setup. Completely free.

Any feedback or contributors are welcome! It's online, source-available, and ready for anyone to use.

Free, Micro AI Code Reviews That Run on Commit

GenAI today is a race car without brakes. It accelerates fast -- you describe something, and large blocks of code appear instantly. But AI agents silently break things: they remove logic, relax constraints, introduce expensive cloud calls, leak credentials, and change behavior -- without telling you. You often find out in production.

git-lrc is your braking system. It hooks into git commit and runs an AI review on every diff before it lands. 60-second setup. Completely free.

In short, git-lrc helps Prevent Outages, Breaches, and Technical Debt Before They Happen
