Video demonstrating bug

Resizing Systemsettings window in sidebarview is visually unpleasant due to slow redraw speed. There are glitches and a black bar stretching to the empty space until redraw completes. See attached video for a demonstration. Maybe this bug is related with bug 386190.
Comment 1 Marco Martin 2018-07-20 14:49:42 UTC
due to the combination of QQuickWidget and X11
on wayland is faster, the best scenario will be when whole systemsettings is ported to qml instead of container objects

This has gotten significantly better for me over the years. Feels fixed-ish for me. Is anyone able to reproduce the issue with Plasma 5.26 or later?

Bug catched on video (plasma 5.27)

Bug is reproduced with Plasma 5.27 both X11 and Wayland (video catches X11, respective software versions also shown). 
The single difference between X11 and Wayland is that X11 bug features black bars while Wayland one features transparent.

I apologize for such a long delay, i was struggling updating plasma on my gentoo installation.

Bug persists on Plasma 5.27, video attached

Yeah, it's only fixed on Wayland. On X11 it's basically unfixable due to the existing infrastructure. There unfortunately isn't any chance it will be improved on X11, sorry.
