Expected Behavior

Text that remains legible at lower resolutions

Current Behavior

Strange pixelation in the image, severe text distortion

Steps to Reproduce

1. Set the output (scaled) resolution to a value lower than the current one. For example, reduce 1440p to 1080p
2. Use a bicubic or Lanczos downscale filter, and watch the recording or stream.

Anything else we should know?

Bilinear and Area filters don't distort the text and work as intended.
This issue had already been resolved here, but subsequent changes brought the problem back:

could you upload the recordings in question here?
because given those screenshots you posted are all in 2560x1440, that means they have been re-upscaled after obs' recording, and as such aren't a good showcase

Also fyi, you have set it to 1792x1008, which is not really 1080p (but that's secondar)

My mistake. I attached the wrong log.
In the video, you can see that the text in the OBS interface is distorted as well.
