      @Christoph-Hart Here's an example of what happens when we load CUBE standalone at 125% with our login view:

      WebView Not Scaling on Startup (720p).gif

      The WebView doesn't scale to the 125% setting like the rest of the interface. Maybe there just needs to be a check on startup?

        @Casey-Kolb no the webview examples in the tutorial scale correctly when restarted. I noticed that there is a small delay in the login popup. Maybe it happens only if the visibility is changed after startup, I'll check that.

          Actually the preset browser example had the same issue. I've fixed it by introducing a small delay for the scale factor update - it seems that if the webview isn't loaded, then the scaling update will be ignored.

          Let me know if that helped.

            @Christoph-Hart Excellent! I'll try it out.

              @Casey-Kolb Actually I found a better fix - the previous one was relying on a timer delay which might work, but now it's much more reliable because it executes the scale factor update when the DOM is loaded.

              Let me know if that's better. I need to test this on Windows tomorrow, but on macOS it's much more stable IMHO.

                @Christoph-Hart Yep, this worked like a charm on Mac.

                  One thing I noticed is that now you cannot use window.innerWidth / window.innerHeight in your JS code anymore as this will be initialized correctly once but will not be updated correctly when the scale factor changes. Instead, just use the actual size of the webview as fixed pixel value, then it works.

                    @Christoph-Hart quick side question , if we have audio being streamed via the browser from a web url source ( context being able to preview a demo of a sound etc.) I am assuming that this will not play through HISE. Might there be a way to be able to set this via scripting ? :)

                      @Brian Getting access to the webviews audio output is not possible but if it's just for streaming a demo track you could just call a HISE function from your JS that will download the particular file and start previewing it.

                      Webview code:

                      <button onclick='onPreview("beat.wav")'>Preview</button>
                      
                      <div id="valueDisplay">This will show the preview progress</div>
                      
                      <script>
                      window.onFileLoad = function(message)
                      {
                        document.getElementById("valueDisplay").innerHTML = message;
                      }
                      </script>
                      

                      HISE:

                      inline function playFile(f)
                      {
                      	local channels = f.loadAsAudioFile();
                      				
                      	for(c in channels)
                      		c *= 0.125; // apply -12dB gain
                      		
                      	Engine.playBuffer(channels, function(args, obj){
                      		wv.callFunction("onFileLoad", "Position: " + obj);
                      	}, f.loadAudioMetadata().SampleRate);
                      }
                      
                      function onPreview(args)
                      {
                      	Server.setBaseURL("https://hise.audio");
                      	
                      	var f = FileSystem.getFolder(FileSystem.Desktop).getChildFile(args[0]);
                      	
                      	if(f.isFile())
                      	{
                      		playFile(f);
                      	}
                      	else
                      	{
                      		Server.downloadFile(args[0], {}, f, function [f]()
                      		{
                      			var message = "Downloading ";
                      			
                      			message += Engine.doubleToString(this.data.numDownloaded / 1024.0 / 1024.0, 1);
                      		    message += "MB / " + Engine.doubleToString(this.data.numTotal / 1024.0 / 1024.0, 1) + "MB";
                      		    
                      		    wv.callFunction("onFileLoad", message);
                      		     
                      		    if(this.data.finished && this.data.success)
                      				playFile(f);
                      		});
                      	}
                      }
                      
                      wv.bindCallback("previewFile", onPreview);
