What to do ? After adding Gtk is still the same Warning.
Win 7 , I preparde special USER JuliaPro_v1.3.1-1 for this instalation JPRO. In Atom was added uber-juno

Yeah, I wasn’t a huge fan of adding that warning. It’s meaningless, and nothing’s actually changed. But I’m not the Gtk.jl maintainer anymore.

See the github issue below for an explanation of the warning. If the mentioned issue doesn’t affect your use-case, you can safely ignore the warning.

Somebody who actually uses Gtk on Windows in real life should check whether Warn on windows by SimonDanisch · Pull Request #467 · JuliaGraphics/Gtk.jl · GitHub reduces the scale of the problem without causing issues (e.g., dropped events). If so we could at least paper over the problem.

I use a GUI written with Gtk and ImageView from time to time and I can confirm that the workaround proposed by @tim.holy improves the experience. I wouldn’t say it fixes it 100% because occasionally I see stutters, but it’s better. Just modify according to the comment, build Gtk and give it a try.

After changing singnals.jl tmout_min::Cint = (uv_pollfd::_GPollFD).fd == -1 ? 10 : 5000

winston is lazy …


> for i=1:100

@time display(scatter(rand(100),rand(100)))
       end
FramedPlot(...)
  0.958385 seconds (1.23 M allocations: 61.319 MiB, 1.73% gc time)

...

Plots also

Plot{Plots.GRBackend() n=1}
  0.212880 seconds (1.23 M allocations: 25.355 MiB, 11.91% gc time)
Plot{Plots.GRBackend() n=1}

Plot{Plots.GRBackend() n=1}
  0.199911 seconds (1.23 M allocations: 25.353 MiB)
Plot{Plots.GRBackend() n=1}

But on this same machine in clear REPL of Julia 0.7 all workig fast (but I must manualy run gksqt.exe). Looks problem is in Julia PRO.

Hi Paul,

It is great that you found a way round GTK problem which I documented:

https://discourse.julialang.org/t/serious-issue-julia-language-keyboard-lag-typing-very-slow/32081

I use Winston since it seems to date to be the fastest plotting package, as I require making a number of plots. Unfortunately I did not find a better alternative solution.

You are speaking to a non computer scientist, so what simple steps must I perform to avoid the Gtk problem?

Many thanks for any help you may provide,
Joseph

For my is not the some problem, VS and ATOM are not siimlar.
Just use only REPL Julia :slight_smile: Studio ,Atom, all are slow on win ! :slight_smile:
I checked Linux, is the same , Win7 and Julia on Vbox or just on HD is fastest!
Win10 is not system … it is some like jam :slight_smile:
