Hi everyone. There might be an issue regarding responsiveness... Before I open an issue on GitHub, would someone please kindly verify if this is reproducable? Running a short demo on Ubuntu 20.04 causes a Compose for Desktop app to become unresponsive if the theme is switched while the app is running.

So, on Ubuntu 20.04
• run this app (button presses print hello
• While the app is running, open Settings and change the scheme to/from dark mode
• now button clicks no longer print something
package com.thomaskuenneth

import androidx.compose.desktop.Window
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.material.Button
import androidx.compose.material.Text
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier

fun main() = Window {
Box(contentAlignment = Alignment.Center,
modifier = Modifier.fillMaxSize()) {
Button(onClick = {
println("Hello")
}) {
Text("Hallo")
}
}
}

Created an issue with video clip: https://github.com/JetBrains/compose-jb/issues/257#issue-782104889

@Thomas the video appears to be corrupt in your issue.

I'm on ubuntu 20.04. I shall try in max. 1 hour your issue and come back

[Thomas]

Thanks for pointing this out. Hm. On Windows inside Chrome the clip plays fine. Does it not show at all, or is the content scrambled? Anyway, thanks a lot for trying on your machine

[Alexandru Hadăr]

Doesn't show at all. I'm on firefox on Linux

[Alexandru Hadăr]

On chrome I can play it, though

[Thomas]

There's a question on Ask Ubuntu reagrding Firefox not playing MP4s, and the posters say some H.264 stuff might be missing... Have not tried myself because my Ubuntu sits inside a VirutalBox, so using it primarily for testing purposes... https://askubuntu.com/q/1170482

@Thomas
I can confirm your bug.
Also, if you resize your window, it does not resize the content.

[Alexandru Hadăr]

Looks like a complete freeze to me, because I can't close the window either

[Thomas]

Yes, that's what I notice, too. Should probably add this to the issue. Thanks a lot for checking this. Came across this during my investigations regarding Dark Mode (maybe you have seen my posts here)

[Alexandru Hadăr]

Yeah, I remember.
Glad I could help

[Thomas]

Much appreciated
