Hi @b19hanru thank you for the report! I think I was able to replicate this! Seems like this error happens when you completely decrease the size of the place where the selected plot is shown and try to selected another plot while having the Fit plot to the pane size option active:

Seems like we need to add a minimum size to the place where the currently selected plot is shown @ccordoba12 ?

Seems like we need to add a minimum size to the place where the currently selected plot is shown @ccordoba12 ?

Or perhaps a max width to the thumbnail bar. I mean, it doesn't make much sense to make it reach the full width of the pane (half of it should be good enough).
