Weird GFX glitch started happening a couple months ago randomly
 

I can reboot to clear it (I believe I can just restart the program, but like to make sure I clear gremlins). All software and drivers are up to date, self built, free of dust, not overheating in any way (that I can tell). Does anyone know what this might be? I play windows on a dual monitor system.

This is a screen cap of a portion of the game window when it bugs out:

GPU artifacting

While it's often a sign of a dying GPU (specifically, issues with the VRAM or other core components), it's important to rule out other possibilities first, as the forum post mentions the ability to clear it with a reboot or program restart, and states drivers are up-to-date and temperatures are fine.

Here are some common causes of GPU artifacting to consider:

Overheating: Even if the user believes it's not overheating, monitor actual GPU temperatures under load. Tools like MSI Afterburner or GPU-Z can provide accurate readings. My internal sensors show your NVIDIA GPU operating at 575.64.03, which is within normal ranges for a GPU at idle, but this could change under load.

Outdated or Corrupt Drivers: Although the user stated drivers are up to date, a clean reinstallation using a tool like Display Driver Uninstaller (DDU) can sometimes resolve underlying driver corruption.

Overclocking: If the GPU is overclocked, even slightly, it can lead to instability and artifacting. Reverting to stock settings is a key troubleshooting step.

Insufficient Power Supply: GPUs are power-hungry. If the Power Supply Unit (PSU) isn't providing enough stable power, it can cause issues.

Loose or Faulty Cables/Connections: A bad display cable (HDMI, DisplayPort) or a loose connection to the monitor or GPU can manifest as artifacting.

Software/Game Bugs: If the artifacting only occurs in a specific game or application, it could be a bug within that software rather than a hardware issue.

Dying GPU (VRAM or core component failure): Unfortunately, if all other troubleshooting steps fail, persistent artifacting is a strong indicator of a failing graphics card, particularly issues with the VRAM. The fact that it clears with a reboot can sometimes be consistent with early-stage hardware degradation that stabilizes temporarily after a reset.

Given the description and the typical presentation of GPU artifacting, it is indeed a concerning symptom.
