I have reported this at the Plots github repository but maybe someone here has already seen this.
A new, seemingly incorrect plots behavior.
In the repl, just use Plots and make any plot:
using Plots
plot(1:5). # or any other plot...
With the gr backend, a gks QtTerm window opens displaying the correct plot.
However, the command produces this output in the REPL:
2025-03-24 11:24:03.189 gksqt[2401:3693999] +[IMKClient subclass]: chose IMKClient_Modern
2025-03-24 11:24:03.189 gksqt[2401:3693999] +[IMKInputSession subclass]: chose IMKInputSession_Modern
The only way out of this is crl-c. This make it impossible to use a sequence of plot commands (or not conveniently, at least…). It is possible to follow up with a plot!(…) command because the running instance of Plots knows the state and can generate another updated plot windown.
I haven’t ever seen this behavior from Plots and the plot command before.
