Start menu: if the comment in the tooltip is long, the tooltip flashes; if the
comment is short, the tooltip stops flashing.
SUMMARY
I am experiencing a flickering tooltip issue in the Plasma Application Launcher
(Kickoff) when hovering over application icons that have a long "Comment" field
in their .desktop files.
In some cases, when navigating through the menus, the tooltip displays
correctly (without blinking) but it is rare, random, and I cannot reproduce it
reliably.
_________________________________________________
STEPS TO REPRODUCE
1. Open the Application Launcher (Kickoff) menu (default menu from the taskbar
or Super key).
2. Hover the mouse over an application entry whose .desktop file has a long
Comment (e.g., Tor browser in my example).
3. Observe the tooltip behavior.
Actual result:
The tooltip appears briefly, then disappears, reappears, and loops in a
flickering/appear-disappear cycle. This happens continuously while the mouse is
over the icon.
Expected result:
The tooltip should appear stably and remain visible as long as the mouse hovers
over the entry, without flickering or disappearing.
_________________________________________________
Additional information:
The issue is directly related to the length of the Comment field in the
.desktop file: shortening the comment like in my video makes the flickering
disappear completely.
This is not caused by the tooltip overlapping the mouse pointer position
(unlike bug #510860 or similar pointer-overlap issues). The flickering persists
even if I carefully position the mouse to avoid any overlap.
It occurs on KDE Plasma 6.5.5 (tested after clean update; no custom
modifications to Kickoff).
I found a report with similar behavior in KDE 6.4.5 which should be related to
cursor coordinates, and which should be fixed now.

In my case, when navigating between menus and scrolling with the wheel,
sometimes the tooltip (long text) displays correctly, but it is hit or miss and
I cannot reproduce the correct behavior with certainty.
