When I turn on the computer(windows 10)
Problems will happen

Weird issue!
The FormatUnavailable error should be catched by the golang glfw wrapper: go-gl/glfw@e9b2113

And PostEmptyEvent shouldn't panic with this error https://github.com/go-gl/glfw/blob/9b86c984c866400dc34182d3a6aaf4cb5be0a4cf/v3.3/glfw/window.go#L1005
https://www.glfw.org/docs/latest/group__window.html#gab5997a25187e9fd5c6f2ecbbc8dfd7e9

Please open an issue on go-gl/glfw (issue not related with this project).
But maybe what's happening is a GLFW_NOT_INITIALIZED error is thrown, then a FormatUnavailable error is thrown concurrently?

Could you more precisely describe what you mean by When I turn on the computer(windows 10) what are the step/configuration to reproduce the error ?

[leedstyh]

same issue here, @itMicmouse have you figure out how to fix this?

[zhileichen]

@pchampio we are coming into the same issue. The crash happens randomly, mostly happens when texting with keyboard.

[zhileichen]

crash at this line: https://github.com/go-gl/glfw/blob/9b86c984c866400dc34182d3a6aaf4cb5be0a4cf/v3.3/glfw/error.go#L178

[leedstyh]

Yeah @zhileichen I comment out this line and the app works fine. I'm pretty sure my app has nothing to do with clipboard, not sure why panic on it.

[pchampio]

Does hover run -b '@fix/post-task-panic' fixes this issue ?
(with the latest version of hover, the -b flags need to be used with: go env -w GOPROXY=direct)

[pchampio]

Or hover build linux -b '@fix/post-task-panic'

[kechkibet]

Hi,
On running the above command i get the following error:
hover: Downloading 'go-flutter' '@fix/post-task-panic'
go get github.com/go-flutter-desktop/go-flutter'@fix/post-task-panic': invalid github.com/ import path "github.com/go-flutter-desktop/go-flutter'"
hover: Updating go-flutter to '@fix/post-task-panic' version failed: exit status 1

Kindly advise.

[pchampio]

Can you try go env -w GOPROXY=direct and run hover build linux -b '@fix/post-task-panic' afterwards ?
Or maybe something like this: https://stackoverflow.com/questions/20458796/unrecognized-import-path-with-go-get

[kechkibet]

Got it to run without the quites i.e.
hover build windows-msi -b @fix/post-task-panic

[pchampio]

Does it fixes the issue ?
can you provide some logs

[kechkibet]

i have sent msi for testing, is there a way to capture logs on release build?
