Upgraded to Fedora 42 beta (Linux fedora 6.14.0-0.rc7.56.fc42.x86_64)
Mesa 25.0.1
LLVM 20.1.0 (Vulkan API 1.4.305)
Same behavior.

Found another sample with same problem.

When https://threejs.org/examples/webgpu_cubemap_adjustments.html
in maximized windows: all is Ok.
When windows in straight state - it's gets broken.

With dom.webgpu.allow-present-without-readback = false all works and looks fine with all samples.
