Hi acdha,
1. You can go to http://feedback.azure.com/forums/247748-azure-remoteapp and share your feedback with the Remote App team. They really want to make it as useful as possible and it is still on Preview so now is the moment to influence the team
3. Yes, we are working on it and should be fixed soon.
Regarding the older versions of IE, unfortunately we are running on top of Server 2012 so we are locked to IE11+. At this moment you can use the dev tools and change the compat mode and we are thinking about adding Enterprise Mode to the service so you can test on "IE8".
Are bugs related to Remote Desktop performance best reported against the client or Remote App? It doesn't appear to support bitblts so simply moving a window is extremely jerky and things like CSS transitions are basically a slideshow.
Enterprise Mode would be useful since that's getting a bit of traction as an alternative to staying mired in IE8.
There is no GPU acceleration. When running IE through RDP we default to software rendering and unfortunately there isn't anything we can do about that :(
Not even old-school acceleration like we used to have in the 90s? I thought RDP used to at least support things like "move this rectangle to a new position" for the performance win over things like VNC.
