Summary0008428: Crash when opening a-* plugins
DescriptionSince 6.3 (which from what I understand introduced new gui to a-* plugins), Ardour crashes when I open any of them (tried with a-eq, a-compressor and a-delay).

Adding an a-* plugin works, but whenever I try to open the plugin window, it shows a black window for a few seconds, Ardour then freezes and crashes a few seconds later.
Steps To ReproduceAdd a plugin like a-eq to a (midi) track, double click on the plugin to open it, wait for crash.
Additional InformationRunning Ardour on latest Windows 10 Professionnal 64bit version. Using a laptop with Optimus (Nvidia 1070 and Intel chipset).

CPU: Intel Core i7-8750H CPU @ 2.20GHz
GPU: NVIDIA GeForce GTX 1070
GPU2: Intel UHD Graphics 630
Audio interface: Focusrite Scarlett 18i8 USB

Do other openGL plugins work? e.g. x42-eq or any Harrison XT-* or overtoneDSP ones.
If not, a common issue there are outdated video drivers and updating the driver fixes this.

PS. meanwhile you can right-click > Edit with generic controls.

So, I updated the NVIDIA drivers to the latest, and still crashed on both a-* plugins and the Harrison Consoles ones.

However, I made Ardour run on Intel integrated graphics (Intel UHD Graphics 630) and it works.
So there is a fix, but I'm not sure exactly why it is so.
