The scrollbar keeps flickering when typing

[katwalk]

The scrollbar on the right keeps flickering whenever I'm typing Chinese with an IME. This isn't a new issue; it's been happening for a long time, and I used to ignore it. However, the constant flickering in my peripheral vision can be distracting when I'm trying to focus, so I figured it was finally time to report it. Fixing this would definitely improve the user experience. Hope you can look into it.

Small discussion about this bug in the github https://github.com/Alexey-T/CudaText/issues/6267 , but we cannot find the reason yet, bug happens randomly.

There is a function:
Auto-show auto-completion after typing N word-chars (0: disabled).
Option is (mostly) for lexer-specific configs.

This function will also lead the scrollbar to flicker.
Is it because of the small pop-up window?

I don't see this problem on Linux-gtk2 version, and I will return to Windows pc only later, in n months.
on this linux version, I have LSP with 'pylsp' server configured, I type chars (or I setup for python: "autocomplete_autoshow_chars": 2 , and then i type chars). and I don't see the flickering of the custom-painted scrollbar.

I captured a GIF picture.
When I type word "click" between script and script, the scrollbar will flicker.
Please refer to the attached gif file.

yes, I got some other person's windows 10 pc, and tested, i can see this flicker when in HTML file autocompletion is called for e.g.
<im

maybe it will help to to find the reason.

I need windows 10 pc with the installed IDE on it, then I will dig the problem better. currently other person's pc don't have IDE installed.
