blank gray screen

### Useful information: Please, try to gather as much of useful information as possible and follow these instructions: - **Version:** - Run this command: `wayvnc -V` - Provide context, including but not limited to - Command line arguments - Special environment variables, if any - Which wayland compositor are you using? Which version? - What VNC client are you using? - Did you configure your VNC client in a specific manner? - Linux distro/operating system - Kernel version - Graphics drivers - Try to reproduce the problem while capturing a **trace log:** - `wayvnc -Ltrace | tee wayvnc-bug.log` - Get the **stack trace**, in case of a crash: - If you have `coredumpctl`, you can gather the stack trace after a crash using `coredumpctl gdb wayvnc` and then run `bt full` to obtain the stack trace. - Otherwise, you can either locate the core file and load it into gdb or run wayvnc in gdb like so: - `gdb --args wayvnc -Ltrace` - If the lines mentioning wayvnc, neatvnc or aml have `??`, please compile wayvnc and those other projects from source with debug symbols and try again. - Describe how to **reproduce** the problem - Try to think about your problem beyond these instructions and include whatever information that you believe will help to resolve the issue $ wayvnc -V wayvnc: v0.9.1-e4ec935 (makepkg) neatvnc: v0.9.5-36ef59a (makepkg) aml: v0.3.0-0-gb83f357 (makepkg) I've been using wayvnc for a long time and it always worked but a few days back it just stopped displaying the desktop and I get a blank gray screen. I'm using hyprland v0.54.0 on arch. logs: ``` Info: Capturing output HDMI-A-1 Info: >> Acer Technologies KG242Y P 0x05113CAC (HDMI-A-1) 1920x1080+0x0 Power:UNKNOWN DEBUG: ../wayvnc/src/ctl-server.c: 809: Initializing wayvncctl socket: /run/user/1000/wayvncctl DEBUG: ../neatvnc/src/server.c: 2150: Trying address: 0.0.0.0 DEBUG: ../neatvnc/src/server.c: 2165: Successfully bound to address Info: Listening for connections on 0.0.0.0:5900 DEBUG: ../wayvnc/src/ext-image-copy-capture.c: 326: Buffer dimensions: 1920x1080 DEBUG: ../wayvnc/src/buffer.c: 606: Reconfiguring buffer pool DEBUG: ../wayvnc/src/ext-image-copy-capture.c: 470: Init done Info: New client connection from 10.10.10.30: 0x55e10f5573b0 DEBUG: ../neatvnc/src/server.c: 362: Client chose security type: 1 DEBUG: ../wayvnc/src/main.c: 1640: Configuring cursor capturing DEBUG: ../wayvnc/src/main.c: 1667: Configured cursor capturing Info: Starting screen capture DEBUG: ../wayvnc/src/main.c: 1030: Acquired power state management.

Waiting for power event to start capturing ``` or on these lines: ``` ext_image_copy_capture_session_v1#23: error -1: no formats available ERROR: ../wayvnc/src/wayland.c: 265: Failed to dispatch pending ``` if you need any other information please let me know because I probably missed something.
