Does this screen indicate overheating? [Picture Attached]

[itstoohot]

I'm using a Pi 3 B+ as a digital menu using feh and xscreensaver. It runs on a 16:9 tv and the images themselves are only ~1.42MB, so not crazy. I'm using a 2.4amp brand new charger and the pi runs off of it continuously. There are no USB devices hooked up, so the power and HDMI are the only things plugged in. My unit is contained in a 3D printed case with a few ventilation holes, but other than that, there is no heat dissipation method as I didn't think about that before.

What does this screen indicate, and what can I do to fix it?

That is not a Pis normal overheating icon, nor is it the normal location. That looks like something either some software added to the Pi is generating, or it is directly from the monitor.

The normal Pi overheat indication is a small thermometer in the upper right corner of the screen (lower right if that screen hasn't had a rotation set).

Ahh that makes sense! I was frantically searching the internet for that picture using terms like "pi overheating" "raspberry pi overheating flame on monitor symbol" haha. No wonder I couldn't find anything relevant. I appreciate the help! I'm rather new to the world of pi. I've had one for several years but only tinkered on and off in my spare time. Is there any way to remove the screen saver entirely? I grabbed xscreensaver per someones recommendation, but I'm not totally sure what it's for. I thought it was to remove the screensaver? I went through the manual for FEH image viewer so I have a good understanding of it and most of it's commands, but not so much for xscreensaver. I want this menu to run 24/7 without interruption. I would appreciate any help.

Edit:
I went through the xscreensaver manual briefly, and I'm not sure why I even need it. I used this guide:

What purpose does xscreensaver serve in a slideshow with feh? The article's author says he used it to "keep the screen from blanking out" and I followed his instructions on switching to xscreensaver and disabling it. I may have goobered up something.

Thanks

You go into the Screensaver settings from the main menu and change the option to "Disable screensaver". Yeah, it does sound odd that you have to install xscreensaver to be able to disable the default screensaver, but that's the way it works.

By default feh will show all the files in the current directory. It is possible that before you disabled screensaver, you hit the [Print Screen] key. If so a screenshot would have been taken and saved in the current directory.

Installing xscreensaver then setting the mode: disable screensaver works but is a 40MB download and loads a background process.

If you have the latest updates then screenblanking can easily be disabled using the GUI config tool or sudo raspi-config.
In order to use this new method xscreensaver must be uninstalled.
