`vvplay` window stops responding after navigation attempts

[Hsiiiii]

After executing vvplay ./Ply and vvplay ./Pcd , where ./Ply and .Pcd are folders containing .ply files and the .pcd files respectively, the window displaying the point cloud becomes unresponsive after navigating using keyboard. The .ply files are sourced from the Long Dress dateset, and the .pcd files are converted from it by vv convert. When the window becomes unresponsive, the window freezes at certain frame even it was playing, and a message "Unknown" is not responding pops up as the attached image. However, if the window displaying the point cloud stopped being focused (after clicking out of it), the window will continue to play the point clouds without reacting to the navigation control that made it got unresponsive. In the terminal, there's also an error message MESA-INTEL: warning: Ivy Bridge Vulkan support is incomplete. If I only switch between frames using the arrow key, the same issue will still occur. The output of running rustc --version --verbose is

Thanks for the details. I never encounter MESA-INTEL: warning: Ivy Bridge Vulkan support is incomplete before, so I suspect this might be the problem. Our wgpu dependency seems to have something Vulkan related. I am trying to understand the possible cause from this: https://www.linux.org/threads/most-games-from-steam-dont-launch-because-pc-too-old-for-vulkan.47192/.

Could you please try to update the packages through sudo apt update && sudo apt upgrade first?

@weitsang @Shiyuang-scu I am not particularly familiar with hardware and driver related problem, please help to take a look at this.

To isolate the problem, could you try running wgpu examples and see if the examples run correctly?

wpgu also comes with a few environment variables. You can try setting WGPU_BACKEND to gl to see if Vulkan is an issue.

Thank you for your prompt reply.

I tried update the package, they are up to date.

I ran the hello example of wgpu examples with WGPU_BACKEND set to gl, and MESA-INTEL: warning: Ivy Bridge Vulkan support is incomplete popped up instead of the expected output.

I will test it with a new GPU after a device update of our lab. I will get back to you as soon as the new hardware arrived, thanks.
