Windows becomes laggy when opening ImageView #281

Closed marcsgil closed 1 year ago

marcsgil commented 1 year ago

I've encountered an issue with ImageView on my Windows PC. When I open an environment that contains only ImageView and then load the package, my entire OS becomes laggy. The issue persists until I close the Julia session. In the video below, I demonstrate this behavior by pressing the 1 key for a few seconds to show the normal speed. Then, I load the package and press 1 again for a few seconds, showing the much slower response time.

This issue occurs almost every time I try to use ImageView on my Windows PC, including with Julia LTS. However, I don't experience any problems on my Linux machine.

Here's the output of versioninfo():

I can confirm this is noticed in my case too for 1.8.5 and 1.9 for the first time I reproduce this 1111... scenario but when I repeat it after enter again, it goes back to normal speed. When I just open Julia, it utilizes 100 mb of RAM and when I do using ImageView and after , it goes to 368 MB RAM usage.

I have seen it magically going away after I type a few things, but the behavior isn't consistent to me.

Upon seeing this post on Julia Discourse, I discovered that this is a long standing issue with GTK.jl (see here). A simple workaround is to run ENV["GTK_AUTO_IDLE"] = false before importing the package. With that in mind, I'm closing the issue.
