Reproduction Steps

1. set mpv to gpu-api=vulkan and hwdec=vulkan
2. have the nvidia app installed with nvidia overlay turned on (it's on by default)
3. launch a video in mpv and go fullscreen

Expected Behavior

dont be transparent

Actual Behavior

is transparent

Log File

output.txt

Sample Files

I have a weird bug, where if I set my MPV to use vulkan for hw decoding, the player becomes completely transparent when the "Press alt+v to open Nvidia overlay" ribbon briefly shows up. I recorded a video below, where you can see it plays fine while windowed, but disappears when I go fullscreen. Obviously it's easily fixable by either disabling the Nvidia overlay or using d3d11va api, but ideally it wouldn't happen in the first place.

I carefully read all instruction and confirm that I did the following:

• I tested and confirmed that the issue exists with the latest release version or newer.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

Start by reproducing the issue with gpu-api=vulkan and hwdec=vulkan in fullscreen while the Nvidia overlay is enabled, then inspect the attached output.txt log. Compare the fullscreen transition with the overlay notification present and absent; done means mpv remains visible when the notification appears under the reported Windows and Nvidia driver conditions.
