Bus error (core dumped) when starting hyprpicker about hyprpicker

[vaxerski]

compile in debug and in the gdb prompt when it crashes do bt -full

I can't reproduce this anymore. I'll reopen this with the backtrace if it happens again.

[n3oney]

damn, was hoping it was gone, but no luck :(

Program received signal SIGBUS, Bus error.

10 bit?

[n3oney]

10 bit?

nope
unless something randomly makes me switch to it which i doubt lmao

[ModestTom]

Having the same issue with bitdepth intentionally set to "10" in hyprland.conf
monitor = eDP-1,1920x1080@60,0x0,1,bitdepth,10
This exact build was working earlier this week.

[n3oney]

this has stopped happening to me, maybe fixed with some update, idk
i now use hyprpicker with every screenshot and it works fine

[PsyNyde]

happens to me everytime after switching to nixos

zsh: segmentation fault (core dumped)  hyprpicker

[isiko]

zsh: segmentation fault (core dumped)  hyprpicker

Same here

[TailstheFox92]

zsh: segmentation fault (core dumped) hyprpicker
I'm having the same issue too, is there a way to see what's actually causing the issue?

[n3oney]

These might be all separate issues. Please build hyprpicker in debug mode and run it in gdb to get a stack trace, then compare with other issues. My issue was solved.
