Hi, I go on the website with another browser (chrome) but i don't think that it can change the result and the qxl driver is installed on the VM. I don't know how to get the size of the stream created, can you explain me? The test that i made is: open the excel file, in full screen, and going up an down quickly (same test on website). I put log on mjpeg_encoder and stream functions, to observe this stream creation. It takes about 10 seconds to launch a stream detection.
