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")

}

}

}

dont run ubuntu or else i would try. sorry

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

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

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

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.

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)

Yeah, I remember. Glad I could help

Much appreciated
