--screenshots is flipped horizontally && unable to unlock using a 'complied from source' version

[Nephty]

I tried using the --screenshots options, but the result was a horizontally flipped screenshot. After finding no other instance of this issue, I tried to go in the source code and change the transforms in the handle_screencopy_frame_flags method. I compiled my new version and locked my computer. After that, I was unable to unlock and it felt like the password was not even being checked (usually, it take a few milliseconds before the 'wrong' text shows up, but in my case it was instantaneous).

Does anyone have any idea why :

• The screenshot is being flipped horizontally ?
• I'm unable to unlock when using a compiled from source version ?

I also couldn't find the debug log file. If anyone could provide me with the path to the logs, it'd be very helpful.

swaylock -v

swaylock version v1.6.11 (Feb 27 2023, branch 'master')

Running on Fedora Linux 37 (Workstation Edition) x86_64
on Hyprland (Hyprland.x86_64 19.git.e1d7a13333v0.19.1-1.fc37 @copr:copr.fedorainfracloud.org:kasion:Hyprland.git)

PS : when using dnf install, I'm able to unlock just fine, but the screenshot is flipped.

Temporary workaround :

grim /tmp/lockscreenshot.png
swaylock -i /tmp/lockscreenshot.png --effect-blur 5x3

you may need to add swaylock to pam.
try echo auth include login | sudo tee /etc/pam.d/swaylock

This is probably some Hyprland bug because it’s not happening on Sway 1.7–1.8.
