Resizing LV2 in Carla doesn't change the canvas size

[unfa]

I've tested the plug-in in Carla today and resizing does't seem to work.

I can resize the window, but the plug-in still redraws only the same area of it, leaving the rest with garbage.

Carla is not letting the plugin know about the resize.
puglReshape not called, but working in Jalv
@falkTX, perhaps you have an idea of why that is?

Interestingly Wolf Spectrum does resize correctly in Carla (it does not in Ardour though).

Right thats' because Patrick cheated it, he implements his custom resize handle.
This issue is with WM-managed resizing.

I think this is an issue with LV2 in general. I don't know about VST3, but LV2 plug-ins have issues with resizing all the time.
Maybe we're lacking some standardized way of communicating this?

Highly doubtful, I'll dig in Carla later to check what really happens

Ok it comes down to this, an unimplemented in DPF
return 1; // This needs more testing

For reference https://github.com/DISTRHO/DPF/blob/89cbdbba5320c8f8822885b510307bef0c7a428f/distrho/src/DistrhoUILV2.cpp#L509-L510

resizing has been a problematic thing in dpf (partially because of pugl)
I am reworking the dgl/graphics stuff in dpf right now, which should fix this situation but will take some time until it is complete.
You can follow the (re)work at https://github.com/DISTRHO/DPF/commits/pugl-upstream-v2
But not much to see at this point.

Is this still an issue ?
