[BUG] [Windows] White screen upon launching the app and then it crashes #487
Comments
@Qwereder this is most likely a driver issue. Please update your graphics drivers to the latest. chiaki-ng uses Vulkan as that’s required for hdr on Steam deck whereas Chiaki uses the older OpenGL which is probably why that’s working fine. |
same for me :/ |
@MrAuronTV can you post a log from debugview if you open debugview before starting the program. Having said that, this is almost certainly an issue with your pc’s Vulkan drivers. https://learn.microsoft.com/en-us/sysinternals/downloads/debugview |
i have the last nvidia driver :/ 00000001 0.00000000 [7788] chiaki.gui: [libplacebo] Initialized libplacebo v7.349.0 (v7.349.0) (API v349) |
@MrAuronTV looking at your logs it should work based on your driver and gpu and others with that same gpu use it no problem. So it’s likely that there is an installed layer or hook on your computer causing this. Can you turn off the obs hook and try again as that has been known to cause crashes? |
I don't know how it detects obs because it is not launched on my pc |
@MrAuronTV Maybe it’s running in the background? Can you try looking in the system tray and opening task manager and searching for obs? |
no nothing :/ |
@MrAuronTV try opening obs and disabling the capture hook from there and then restart Chiaki-ng and check the debug view logs again It’s currently capturing it somehow. Maybe try searching hook in task manager |
@MrAuronTV alternatively creating a shortcut for chiaki-ng and adding DISABLE_VULKAN_OBS_CAPTURE=1 before the game should prevent the hook from running on chiaki-ng or adding that variable to your system environment variables should prevent the hook from running on any game. |
how to do that? i have shortcut , but how add the command before ? |
@MrAuronTV Create a bat file like
called chiaki-ng.bat or whatever you prefer |
@MrAuronTV if it worked correctly you shouldn’t see that obs hook message in your debugview logs when you launch Chiaki-ng using that shortcut (you can close debugview and reopen to clear the old logs) |
@MrAuronTV let me know if that fixes your issue when you get a chance to try it. |
same issue with bat file :/ 00000001 0.00000000 [14220] chiaki.gui: [libplacebo] Initialized libplacebo v7.349.0 (v7.349.0) (API v349) |
@MrAuronTV it looks like it’s still loading the obs hook. Can you post the bat file you’re launching? |
@echo off |
@MrAuronTV can you try adding DISABLE_VULKAN_OBS_CAPTURE as a system environment variable with value 1 and then restart your system and try launching chiaki-ng again? The obs are saying that's how to turn off the vulkan hook. Also, it hooks all games when they start regardless of obs being open like we're seeing because it has to hook it at the vulkan app start for it to work for Vulkan specifically so it can still cause issues/crashes with obs closed. |
User experience with same situation: problem was solved by deleting all screen capture apps (OBS, bandicam, etc) |
