Lapce crashes on startup (Windows 11)

[lpaulino07]

Lapce Version

v0.3.1

System information

Windows 11
AMD GPU, Adrenaline v24.3.1

Describe the bug

Application crashes during startup. A white rectangle shows up for a few seconds, then closes without any errors.

Additional information

Also tried with latest nightly, same issue. Attached GBD and didn't get any helpful information.

GDB log:

Seems to be fixed. I still get the white rectangle for like a second, but Lapce opens afterwards. I recently had to reinstall graphics drivers, so that might've been the issue. Latest nightly (nightly-39ef70d) works fine as well.

Will leave the issue open for now since somebody else seems to have the same issue in the comments.

[lpaulino07]

The issue is back, but I still think it might be a driver issue. Also, just found out that I need to run Lapce with "-w" if I want to keep in running in the terminal. Therefore, the previous log is not correct. A relevant portion of the new log is:

Thread 108 received signal SIGSEGV, Segmentation fault.
0x00007ffa38a25dcc in vk_icdGetInstanceProcAddrSG ()
   from C:\Windows\System32\DriverStore\FileRepository\u0401413.inf_amd64_997830838cb299a9\B401180\amdvlk64.dll

@SeleDreams would you be willing to post a log to see if we're having similar issues? Since you're using NVIDIA, it won't be an amdvlk64.dll problem, but it might help devs figure this out. Thanks!

[lpaulino07]

In my case, it can be fixed by setting WGPU_BACKEND=dx12 or gl, so it's definitely a Vulkan issue. Unless SeleDreams's crash is also Vulkan related, I will close this issue.

I get this:

[lpaulino07]

Could you post the backtrace? Or if you have a gdb log could you post the relevant portion? Also please try the different WGPU_BACKEND options to see if it's actually a Vulkan issue. If not you might need to create a separate issue.

Or if you have a gdb log could you post the relevant portion?

@asik your issue is #2809

I see. At least in my case it helped me identify it as a Vulkan problem. Thanks for the input!
