[SOLVED] Occasional black bar flickering while using G-Sync compatible on my Acer XFA240

Hey guys,

I've been having an interesting issue with my monitor when I use it with G-Sync. In select games such as the Halo MCC (shown in the GIFs), Minecraft and CSGO, I will get a black bar that flashes on the screen for a split second, which seems to happen every few minutes. My specs are the following:

• Gigabyte RTX 2060 Super
• Acer XFA240h G-Sync compatible Freesync monitor (it's 144hz and 1080p, and I have it connected via the supplied DP cable)
• i5-9600k, stock clocks
• Corsair Vengeance LPX 3200mhz RAM, 16GB
• ASRock z390 Pro motherboard

My NVIDIA control panel settings are the following:

Here's a GIF of the issue in action:

Here's a GIF that shows it a little slower:

Definitely a little puzzling. I'm on the latest driver (446.14), but I had the same issue with the previous one. If anyone's got some insight, thanks in advance!

I've managed to solve this issue for now. It seems Riot Vanguard was the cause of the issue, so I uninstalled it. Maybe the software was interfering with DWM?
