Hovering with the mouse over an interactive plot spams GLMakie error in the REPL

[damianodegaspari]

I am opening this at the suggestion of this Discourse topic.

I am trying to visualize agents based models through interactive plotting.
I created the following MWE by copy-pasting the code found in this page of the documentation.
What happens is that an error (see output below) keeps getting spammed in the REPL while hovering with the mouse over the GLMakie window, even without clicking. However, the buttons “step model”, “run model”, “reset model” seems to work as expected.
The discourse topic linked above (is quick to read and) has a bit more information on how I got to this point, but I think I selected here all the relevant pieces.

Runnable MWE:

using GLMakie
using Agents
using AgentsExampleZoo

model = AgentsExampleZoo.daisyworld(;
    solar_luminosity = 1.0, solar_change = 0.0, scenario = :change
)

model

daisycolor(a) = a.breed
agent_size = 20
agent_marker = '✿'
agentsplotkwargs = (strokewidth = 1.0,) # add stroke around each agent

heatarray = :temperature
heatkwargs = (colorrange = (-20, 60), colormap = :thermal)
plotkwargs = (;
    agent_color = daisycolor, agent_size, agent_marker,
    agentsplotkwargs = (strokewidth = 1.0,),
    heatarray, heatkwargs
)

fig, ax, abmobs = abmplot(model; add_controls = true, plotkwargs...)
fig

Error message (I tried to isolate one of them, as said in the description it seems to be always the same one, spammed multiple times):

[Tortar]

Seems like the hovering accesses a 3d matrix while the plot is 2d and so it errors

[Tortar]

should be fixed by #1092

[damianodegaspari]

Thanks for very quick fix! I will test it as soon as the new version comes out (not sure exactly how to do it before)

[damianodegaspari]

Yes, I can confirm that now the error is gone. Thanks again.

[Tortar]

It was quick fortunately :-)
