KDE Plasma 6.9 fixes desktop right-click memory leak, adds OSD positioning

KDE developers have begun landing features and fixes for the upcoming Plasma 6.9 release, including a resolution for a memory leak that occurred every time users right-clicked files or folders on the desktop in plasma-desktop. The leak, while small in absolute terms (kilobyte scope), would accumulate over repeated interactions. Separately, Plasma 6.9 will allow users to configure the position of on-screen display pop-ups rather than being locked to the default location.

Additional changes include KDE-style password prompts for systemd-ask-password --no-tty on systemd 257 and newer, Plasma Browser integration for the Glide browser, and improved default sizing for desktop widgets to prevent content cut-off. A KWin crash fix when DisplayLink screens are connected is also queued for the Plasma 6.8.3 point release.

Plasma 6.9 desktop and integration changes

• Memory management: The plasma-desktop process no longer leaks memory on each right-click event for files or folders on the desktop; the leak was in the kilobyte range per invocation.
• OSD positioning: Users can now override the default placement of on-screen display pop-ups with a configurable alternative position.
• systemd integration: KDE now renders native-style password dialogs for systemd-ask-password --no-tty when running on systemd 257 or newer, replacing TTY-based prompts.
• Widget sizing: Desktop widgets are now allocated larger default dimensions to ensure content is visible without truncation.
• KWin stability: A crash triggered by DisplayLink monitor connections is being fixed in the Plasma 6.8.3 maintenance release.

Why it matters

The memory leak fix addresses a long-standing quality-of-life issue for heavy desktop users who frequently interact with files through context menus, reducing process bloat over multi-day uptimes. The systemd-ask-password integration and Glide browser support continue KDE's expansion beyond traditional X11/Wayland desktops into containerized and alternative browser environments, reinforcing Plasma's position as a flexible Linux workstation shell.
