Plugin crashes when used in reaper#2

I tried to load the plugin with reaper 6.34, the program crashes (using Ubuntu 20.04): ` $ ./reaper jack: created client jack: setting TIME_CRITICAL = 4 jack: activated client MESA-INTEL: warning: Ivy Bridge Vulkan support is incomplete thread '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value', src/editor/interface/graphics.rs:111:18 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace fatal runtime error: failed to initiate panic, error 5 Aborted (core dumped) ` I guess there is a problem with my gpu. It is an integrated GPU. `sudo lshw -C display` gives ` *-display description: VGA compatible controller product: 3rd Gen Core processor Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:36 memory:62000000-623fffff memory:70000000-7fffffff ioport:3000(size=64) memory:c0000-dffff ` Loading the plugin with ardour seems to work as expected. ~(A minor issue might be that when the plugin is compiled in debug I get an overflow when loading the plugin: `MESA-INTEL: warning: Ivy Bridge Vulkan support is incomplete thread '<unnamed>' panicked at 'attempt to subtract with overflow', src/editor/interface/state.rs:77:20 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace fatal runtime error: failed to initiate panic, error 5 Aborted (core dumped) `)~ (fixed in #3)
