Horizontal Rendering Tear
Hey everyone,
I am experiencing a very specific, frustrating rendering artifact that spans across entirely different programs: Games, Mozilla Firefox, and even the native Windows 11 File Explorer.
Sometimes when there is a sudden asset load or a drastic, full-screen brightness shift (like a cutscene exploding into a pure white exposure flash, or clicking a button that pops up an Explorer window), the loading happens line by line, which i know is normal but you don't usually see this.
The top half of the frame updates to the new scene/theme instantly, while the bottom half is stuck on the pure white frame or placeholder box from a microsecond before.
I've been seeing it a lot lately when i click on an image for example on some website, the same thing happens. Sometimes it loads in 2 frames, where a bit more than the top half is drawn in, the rest is white, then next frame it shows the image normally. Other times, more rarely, you can literally see each line getting drawn in very fast. I didn't pay much attention to all of this until i saw it happen in game (video attached).
it is not just a single bad frame. During the brightness ramp, it looks like the upper part of the frame is already on the current brightness/frame, while the lower part is still showing the previous frame’s brightness.
Some things to note
- My monitor is set to 4K and 144hz.
- GSYNC (Fullscreen) is enabled. VSYNC enabled in NVIDIA App. Disabled in games. For CONTROL specifically, i am capping my framerate to 90 using RTSS.
- NVIDIA Driver is the latest (596.49).
- It is baked into my OBS video files. I'm using Game Capture and HVEC encoder.
- It happens in Windows UI: If I click an upload button inside a web browser for example, when the Windows File Explorer dialog pop-up box appears, the top half draws instantly while the bottom half flashes a solid white block for a single frame before normalizing.
- I've noticed
- No performance issues: The GPU has no frame drops, zero crashes, and zero traditional artifacting (no flashing checkerboards or random colors).
