nw App appearing as black screen. #6152
Comments
please note that the black screen stays until we restart the app. |
Looks like the user data directory was locked -- do you have another instance running? |
No I guess. However,this happens for some specific windows users. Even if that's what is causing this ,how can this happen in between,after the app has successfully launched. |
Anything else seems suspicious to you here?I feel it might very specific to the machine specifications. |
Hello, I am seeing this with 0.23.7 on Windows 10 |
@dsomesh , @quantumproducer , could you provide your tests to reproduce this? I try some tests on Windows 10, all of them work fine. |
Hi,actually we are also not able to reproduce this in house.We are seeing this with only one of our customers which has nw version 0.22.0. It has also been recently reported that the black screen sort of auto heals after some time. |

@dsomesh I found the issue on my end - it was a missing .node binary. Sorry for the false alarm. |
@quantumproducer did it ever recover in your case?For us this issue is random and it does recover if its left like that. |
@dsomesh users have reported the issue fixed. You can view the code and libraries used at http://QuantumPilot.me - free download of RC7. Before I fixed, it was never recovering because it was crashing on loading the node module. |
hi, i have a similar situation on my computer. Repeat steps: nw版本:0.24.3 |

Lenovo p51 with Windows 10 Pro and NVIDIA Quadro M1200. I get the problem while my laptop is in the docking station connected to two additional monitors(3 in total). Doesnt matter which nw.js i use but i tried the latest 0.30 and 0.23 and neither did work. As soon as i dock off the laptop it works without any problem. https://screeps.com/forum/topic/2228/black-window-on-startup/8 |
Same issue as @Dragonisser here. |
@Dragonisser @bjoernneumann does the Chrome or Chromium browser have the same issue? Thanks. |
@daemon-7 this usage is not supported by Chromium gfx stack. |
@rogerwang Chrome 67.0.3396.62 works well. |
What about the Chromium browser (not Chrome) ? |
Just checked chromium 69.0.3451.0. Works as well. |
Is there any difference between NW and Chrome if navigates to 'chrome://gpu' ? You can launch NW with nw --url='chrome://gpu' |
|
Also checked: Chrome: Version 67.0.3396.62 (Official Build) (64-Bit) works fine Im testing with 30.5 Chrome displays chrome://gpu fine NW:

Thanks. I'll fix the blank page of |

Any updates? |

Sorry for not sending the infos. |
I was encountering this issue with NVidia Quadro driver 419.67. All NW.js windows were solid black with a slight flicker. Running NW.js with --disable-gpu worked around the issue. Once I upgraded to 430.39, the issue went away even when GPU acceleration was being used. As my "problem" driver came out after @bjoernneumann's issue was resolved (and he was using 390.77), this seems to be a reoccurring problem that might need further investigation. |
This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions. |
