Compare the above two frames. In the first frame, the moon disappears.

Please, have you tried to reproduce this with latest released version 0.9.5?
Thanks

I have tried the version :
https://github.com/hms-ecosystem/OpenXR-SDK/blob/main/demos/Wolvic-hvr-arm64-release--2022-04-20.apk

here is the
1, The probability of happening is much lower, i think it is a big improvement, This almost never happens when you don't do the rotational displacement of the head.
2，but unfortunately it still happens, especially when moving HMD rotation.
3，However, when you enter the moon rider, even if your VR HMD head does not move @rotation, this phenomenon still occurs.

Ok, I think I have managed to reproduce the glitch with the 2022-04-28 version from https://github.com/hms-ecosystem/OpenXR-SDK/tree/main/demos/ (the 2022-04-20 is no longer there).

I will investigate, thanks for the info.

-- the 2022-04-28 version, it still happened,
and i found a video, someone else use firefox reality on PICO NEO3 , run the moon rider. I think there is the same the bug.
maybe it is a bug from framework?

I think there are two different things here:

1. the screenshots you attached in previous comments. I have personally never seen them, it would be nice if you could provide some steps to reproduce it.
2. the flickering in moonrider. This is something that happened also in firefox reality. It does not happen in Oculus browser, so I suspect it must be something related to the use of WebXR layers (we don't use them in HVR)

Hi Sergio, Please see the following video sent from HVR. They mentioned that in the newest Wovlic version, this happens less often.

here is the new found at newest version which is build at 2022-5-24
I guess some frame rendered abnormal，it caused by the position，and you can see the picture below，here is other fakeed controller （locate at top of the picture below），and the position of the new fake controller，it seems has a delta.

here is the video. you can find the abnormal picture view frame by frame

Thanks for reporting. I've indeed seem similar issues. However I think the problem is not in Wolvic because I've seen this kind of glitches also in the VR UI without opening any application. I'll try to record a video showcasing the issue.

[dingsing2021]

maybe it is a bug from some huawei phone, some model happend.
1, I have try a mate30pro, No such problem occurs.
2, another mate40pro(a special module, early access type) , qilin 9000 chipset, have such problem.

SO I think this issue could be closed.

At this moment I'm almost sure that the problem is in the device OpenGL stack (it might be a driver issue).

@dingsing2021 Any further info. to share? Thanks

[svillar]

I haven't seen this issue for a while. I'll close this

Please reopen if you observe it again
