Created attachment 104036 [details] Screenshot showing small track size Cannot make the size of the video and audio tracks bigger. Used to occupy the entire space below monitor as shown on attachment. Tried to change default settings with no success. Seems to stay that small even when loading views made prior to bug.
Did you click on the track header zoom button? The track size should change when you change the default track height in config, but maybe only by 50% in case you set a zoom for 50% track height. Also, please use the forum for help, unless you can clearly show using an example project that this is a bug.
