Analyzing the video frame by frame it seems like the bookmarks get loaded twice initially (1) and (2), and then the instance (1) is replaced by three menu items: most visited, closed tabs, closed windows - all while the menu is in plain sight!

Not 100% sure whether this is coming from Falkon or from Menu.

Comparison (not bugged):

And you don't see the glitching even for a split-second?

grahamperrin commented 3 years ago

True. There's a split-second of fading out (away from View) to fade in (of History).

NB this is FreeBSD-CURRENT without helloSystem.

If I'm to compare with the Deutsch GUI of Falkon, with KDE Plasma, is this the approach?

– or is the effect limited to Plasma?

probonopd commented 3 years ago

I have set my system language to German but I doubt it makes any difference. I have not changed "Configure Plasma translations".

Thanks. One of these?

grahamperrin@mowa219-gjp4-8570p:~ % locale -a | grep de
de_AT.ISO8859-1
de_AT.ISO8859-15
de_AT.UTF-8
de_CH.ISO8859-1
de_CH.ISO8859-15
de_CH.UTF-8
de_DE.ISO8859-1
de_DE.ISO8859-15
de_DE.UTF-8

Or am I confused?

probonopd commented 3 years ago

Yes, de_DE.UTF-8.

Temporarily use a different locale for the user interface of a GUI application : freebsd

Resolved.

Housekeeping:

Observations:

reproducible on helloSystem with a different LANGUAGE
not limited to the History menu
no duplication (where a page title appears more than once, there are different pages with non-distinct titles).

On helloSystem

The space given to the submenu is initially large enough to accommodate a subset of menu items. As additional menu items appear, the space either:

redraws at different sizes to accommodate the growth (and, maybe, the drop shadow); or
draws first at a size not large enough for the menu items, draws later in an enlarged space on the other side 𣀓𠄳(to trigger this: point at a submenu elsewhere, then revisit the affected submenu).

Five frames from a screen recording. In the first two we see the right side, left side behaviour:
