 screencopy: guard CSCDMAFrame destructor against destroyed EGL context (#1046) 
CUniquePointer::operator bool() only tests the impl_base pointer, not
impl_->_data (the actual managed object). When the CEGL object is already
destroyed — e.g. due to global-destructor ordering — impl_base can remain
alive with _data == nullptr. The previous check `if (g_pEGL)` passed in
this state, causing a null-pointer dereference when accessing
g_pEGL->eglDisplay.

Fix by using g_pEGL.get() which correctly returns nullptr once the CEGL
object's _data has been cleared. Also guard against m_image == EGL_NO_IMAGE
to avoid calling eglDestroyImage with an uninitialised image handle (frames
destroyed before onBufferReady completes).

hyprlock

Hyprland's simple, yet multi-threaded and GPU-accelerated screen locking utility.

Features

  • Uses the ext-session-lock protocol
  • Support for fractional-scale
  • Fully GPU accelerated
  • Multi-threaded resource acquisition
  • Blurred screenshot as the background
  • Native fingerprint support (using libfprint's dbus interface)
  • Some of Hyprland's eyecandy: gradient borders, blur, animations, shadows, etc.
  • and more...

How it looks

Docs / Configuration

See the wiki

Arch install

pacman -S hyprlock # binary x86 tagged release
# or
yay -S hyprlock-git # compiles from latest source

Building

Deps

You need the following dependencies

  • cairo
  • hyprgraphics
  • hyprlang
  • hyprutils
  • hyprwayland-scanner
  • mesa (required is libgbm, libdrm and the opengl runtime)
  • pam
  • pango
  • sdbus-cpp (>= 2.0.0)
  • wayland-client
  • wayland-protocols
  • xkbcommon

Sometimes distro packages are missing required development files. Such distros usually offer development versions of library package - commonly suffixed with -devel or -dev.

Building

Building:

cmake --no-warn-unused-cli -DCMAKE_BUILD_TYPE:STRING=Release -S . -B ./build
cmake --build ./build --config Release --target hyprlock -j`nproc 2>/dev/null || getconf _NPROCESSORS_CONF`

Installation:

sudo cmake --install build
