VCV Rack is a black empty window

General system Applications

Hi.
Some time ago VCV was working right since the previous version, but I don’t know if I deleted something or maybe after one EndeavourOS update VCV became a black window, I was waiting the new VCV version, I thought it was going to change, but it is the same black window, this is only in Plasma, it is working perfectly in Gnome.

I tried: deleting the user folder, installing from AUR.
I already asked to VCV, but they don’t know what happens and they are looking for a solution.

Thank you :slightly_smiling_face:

Here is the log file.

This might point to the compositor - try some different settings in KDE (or e.g. disable the compositor) to see if this changes things.

Thank you!
I think I don’t use any compositor, how can I check that?
All Kwin scripts are disabled.
There are no window rules.

what build do you have installed?
yay -Qs vcv

I use the portable version (is the right terrn) I run it from the folder and is the 2.0.5

log do not show any error or missing libs… but could be that.

Look in the KDE settings (the Window Manager section I think?)

If qdbus org.kde.KWin /KWin supportInformation gives you any output, you could grep for Composit.

On Kubuntu 20.04 (with Plasma 5.18.5), I get:

> ~ $ qdbus org.kde.KWin /KWin supportInformation | grep -i compos
Composite: yes; Version: 0x4
compositingMode: 1
useCompositing: true
windowsBlockCompositing: true
Compositing
Compositing is active
Compositing Type: OpenGL
> ~ $

I don’t know if the above code works on the latest Plasma.

(The toggle to turn on/off compositing in X11 is Shift+Alt+F12.)

Thank you!
Is not active.
I’m using the default theme, icons, style, decorations, there are not any desktop effects, no window’s rules.

Does it make a difference if you enable compositing?

GNOME has compositing enabled by default.
