It could be that the error depends on the window manager being used. When I switch to i3-wm , I’m getting the BadWindow error with DemoRunner from latest juce develop branch (non-fatal, though, but it seems to be fatal for plugins). Here is the stacktrace: ```auto #0 0x00007ffff5da1190 in _XError () from /usr/lib/x86_64-linux-gnu/libX11.so.6 #1 0x00007ffff5d9dff7 in ??
