Laria Carolin Chabowski fc2c5c373b NotificationServer: Reposition notifications on screen resolution change 
Previously notifications were (partially) drawn outside the screen rect if
they were created before changing the screen resolution to smaller
dimensions. This prevented the user from dismissing the notification as the
close button was no longer clickable.

SerenityOS

Graphical Unix-like operating system for x86 computers.

Build status Fuzzing Status

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
