Crash, maybe related to drawing failure for widget, gtkmm, out of memory

## What happened Waybar crashes or freezes, at random times. ## What was expected Waybar to be stable, as it was. The update to appears to have changed something. ## Step to reproduce This is where it gets tricky. Waybar freezes at times. I can more or less reproduce it when I play a video in a workspace (using Hyprland) and switch to other workspaces while the video is playing. Video can be Zoom or YouTube. At other times, it just freezes. In the logs, I cannot see anything unusual: ```log [2026-04-21 09:18:18.272] [info] Using configuration file /home/yg/.config/waybar/config [2026-04-21 09:18:18.272] [info] Including resource file: $HOME/.config/waybar/Modules [2026-04-21 09:18:18.272] [info] Including resource file: $HOME/.config/waybar/ModulesWorkspaces [2026-04-21 09:18:18.273] [info] Including resource file: $HOME/.config/waybar/ModulesCustom [2026-04-21 09:18:18.273] [info] Including resource file: $HOME/.config/waybar/ModulesGroups [2026-04-21 09:18:18.273] [info] Including resource file: $HOME/.config/waybar/UserModules [2026-04-21 09:18:18.276] [info] Discovered appearance 'dark' [2026-04-21 09:18:18.305] [info] Using CSS file /home/yg/.config/waybar/style.css [2026-04-21 09:18:18.313] [warning] Failed to open bar ipc connection: Socket path is empty [2026-04-21 09:18:18.317] [warning] 'swap-icon-label' must be a bool.
