Wrong display after resizing the plugin window in Carla host

[unfa]

I'm using Carla-git and newest x42 plugins from KX Studio repositories underl Linux mInt, with KDE5 desktop.

When I try resizing the SiSco window, it doesn't seem to redraw itself properly.

(The funky gradient effect is because my window manager makes windows semi-transparent when I resize them and on black background it gets darkened and fed back into the draw buffer.)

Can you check if the standalone jack-app x42-scope is also affected?

If the "screen width" text in the footer is any indication, the GUI itself never receives a resize request. I can't reproduce the issue here but I neither have Carla nor KDE5 around.
