Plasma 6.8: what the 50 ms panel delay actually changes

KDE’s August 22 development report lists a shorter panel delay for Plasma 6.8. The timer falls from 500 to 50 milliseconds, but that number describes a specific wait in auto-hide behavior rather than the animation speed of the whole desktop.

The stated panel grace interval falls from 500 to 50 ms after pointer exit, a 90% shorter wait. The lines share a zero and scale; animation time is not measured here.

Find the timer behind the headline

The weekly KDE report links the change to plasma-workspace merge request 6885. Its description identifies m_unhideTimer, which controls how long an edge-activated panel remains visible after the pointer leaves. The change shortens that grace interval from half a second to 50 ms.

The arithmetic is straightforward: the wait is one tenth as long, or 90% shorter. That does not make the hide animation ten times faster. Rendering, animation and the user's pointer path are separate parts of the visible sequence. A stopwatch covering all of them would measure a different quantity.

What should feel different

Imagine moving the pointer to the screen edge to reveal a panel, then moving it back into a window. In this specific interaction, a shorter grace interval can clear the panel sooner. It does not promise that every panel disappears 50 ms after every possible mouse event; visibility modes and the rest of the interaction still matter.

For a proposed comparison, keep the same screen, panel visibility mode and animation settings. Repeat the same edge-entry and pointer-exit sequence, then note separately when the wait ends and when the panel has finished moving. This isolates the intended behavior more effectively than comparing two unrelated desktop recordings.

PeopleAreGeek has not measured this change on two installed Plasma builds. The illustration explains the stated timer values, not an independently captured benchmark.

Do not copy a setting from an earlier revision

The merge-request discussion includes an earlier configurable variant, but its configuration key was removed during revision. That history is not a reason to publish instructions telling readers to add the discarded key. Use the interface and documentation of the version actually installed.

The same weekly report mixes work targeted at Plasma 6.8 with fixes for other release branches and KDE Frameworks. One example aimed at 6.8 is finding System Settings pages using English terms even in a localized interface. Those entries should not all be presented as features already delivered by one current update.

The practical takeaway is specific: the auto-hide wait is being reduced on the stated development branch. Check your distribution's Plasma version and release notes before expecting the behavior on an existing desktop.

Explain the specific post-pointer-leave timer change; do not confuse it with animation duration or claim the abandoned setting is available.
