When the B580 is running under Vulkan

lhmxing — Wed, 01 Apr 2026 11:23:18 GMT

When using the B580 graphics card on Windows 11 25H2, games running under the Vulkan graphics API are forced into fullscreen mode instead of borderless windowed mode. During this time, the color gamut and brightness of the entire system are forcibly restricted. Even after closing the game, the color gamut and brightness restrictions do not revert (though this should be an issue on Microsoft’s side). Nevertheless, I still hope to see improved support for Vulkan as soon as possible, especially regarding borderless window functionality.

I apologize for not replying to you in a timely manner, as I have been busy with other matters recently. Regarding your question, my response is as follows:

First, this issue only occurred after I installed this new graphics card in my computer; there were no such problems when I was using my previous AMD graphics card.

Second, I tried launching the game in DirectX 11 mode, and it worked fine—borderless window mode started normally.

Third, I believe this may be a common issue when using Vulkan as the graphics API. If I can only report this for one game, I would choose Arknights: Endfield.

Lastly, I have attached my SSU log for your reference.I have also recorded a video for your reference and comparison, but unfortunately it is too large to be uploaded.
