Virtual machine pixel remoting

Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for changing virtual machine user interfaces. One of the methods includes detecting, for a remote session, a first resolution for a content presentation area in a web browser, generating, using the first resolution, a first stream of pixels representative of a user interface, providing the first stream of pixels for display in the web browser, receiving input indicating a change to a resolution of the content presentation area in the web browser, detecting a second resolution for the content presentation area in the web browser, generating, using the second resolution, a second stream of pixels representative of the user interface, and providing the second stream of pixels for display in the web browser by the client device.
