Graphical glitch when using a shortcut that disables the editor and that extends the Preview-tab

[ralf3u]

Description
When using some shortcuts of switch-views of geanylua (Toggle editor 1, Toggle editor 2 and both Switch Views), then one can see the scrollbar of the Preview-tab for a part of a second somewhere else. If for example the sidebar is on the right side, and if the widths of editor and sidebar are about 3:1 (see image 1), then, after having pressed the shortcut Toggle editor 1, the sidebar is moving to the left side (see image 2), so that the scrollbar of the Preview-tab is more on the left side, and then the content expands to the right side (see image 3). The images are screenshots from a video that I did with a digital camera.

Possible explication
The graphical glitch does not appear in the tab Documents of the sidebar when the plugin Preview is deactivated in the list of the Plugin Manager. So, it could be that the webbrowser component of the Preview-tab loads slowly.

History
This issue is based on the knowledge of xiota/geanylua-scripts#9.

System
Lubuntu 24.04
Geany 2.0

Most likely not much I can do about this. Problem seems to be related to rendering speed of the webview. Widgets probably aren't meant to be repeatedly shown and hidden.

Will leave issue open in case some solution or workaround is found.

What I forgot to mention in the report:

The graphical glitch does not appear always when pressing some shortcuts. But if the graphical glitch appears, then it appears when toggling only the first time for example from only editor to only sidebar. If I continue to toggle, then the graphical glitch does not occur any more.
If editor&sidebar are shown again side by side and then if I toggle again from only editor to only sidebar, then:
If the graphical glitch appears, then it appears again when toggling only the first time for example from only editor to only sidebar. If I continue to toggle, then the graphical glitch does not occur any more.

The graphical glitch only appears if a scrollbar exists in the preview-tab, is it the vertical scrollbar or the horizontal scrollbar or both scrollbars.
