Do you think that 7+ Taskbar Tweaker causes the issue? Or is it just an idea for something that the tweaker could fix?

That should be fixed in v5.2.9.3, among other things. Please try it.

Когда финальная версия будет готова, будет опубликован пост в блоге.

Это известная проблема. На эту тему уже есть топик:

Please try the "scroll_no_wrap" advanced option in 7+ Taskbar Tweaker beta v5.2.1.4.

Can you please check, do the issues happen if no options are set in the tweaker? If that's the case, can you find out which option causes the issues?

I've replied in the GitHub issue.
