Gui is not initialized within dual-screen machine.

[Levitanus]

I use two monitors: 1920x1080 from left and 1080x1920 from the right side (I can't remember where I can get the real Xorg canvas dimentions). And many of plugins: by Ignite Amps, Liquid Sonics etc. are opened in black. GUI can be updated within re-rendering of their area, for example, by touching the knob or button.

I'm quite sure it's LinVST issue as carla works goon on dual-screen machine. Actually I was quite surprised these plugins work good on one monitor, as yesterday I was forced to move and could get only one screen with myself, which opened the problem.

As far as I know, LinVst used to have issues with dual monitors a long time ago, but I'm pretty sure it got fixed after this issue popped up https://github.com/osxmidi/LinVst/issues/43

hmm, I'll double-check, but I've built it from this source somewhere at the last spring...

Make sure you also use package:

lib32-libxinerama

At least that's how it's called on Arch - it fixes Wine problems for multi-monitor output

@keybreak, Thanks, I'll try at evening

hmm, I think that is it, was installed
