Horizontal and vertical lines appear when window is scaled
Important Information
Provide following Information:
- mpv version
mpv v0.38.0-63-gb364e4a6 - Windows Version
Version 22H2 (OS Build 19045.4291) - Source of the mpv binary: https://github.com/shinchiro/mpv-winbuild-cmake/releases/tag/20240421
- Possible screenshot or video of visual glitches
Reproduction steps
mpv --no-config --vo=gpu-next --autofit=50% "video_[B4DB49AE].mkv"
Expected behavior
No horizontal or vertical lines when the window is scaled down.
Actual behavior
Horizontal and vertical lines, sometimes both to form a grid-like pattern appear, not every time but I would say they appear once every 5 times I go from full screen to windowed. Often they appear at the start of the playback when it is already windowed and then go away when fullscreened. They never appear in fullscreen, only when windowed

Can you install latest Intel GPU driver? 10.18.10.5161 are quite old and Intel has a history with completely output on certain drivers.
Unfortunately my hardware is quite old and has reached EOL, 10.18.10.5161 from august 2020 is the latest driver I can use.
If it helps, the issue does not happen with --profile=fast and did not happen when I was on some version of 0.36. Only started to occur when I updated from 0.36 (sorry, I don't have the exact version number now) to v0.38.0-63-gb364e4a6 a few days ago
Can you use --show-profile=fast and apply each option independently and see which one fixes it?
I also have this issue on similar hardware and I find that only 16:9 and wider videos seem to have this issue. 4:3 aspect videos are unaffected.
In the absence of old Intel hardware, this can be reproduced in a Windows virtual machine.
