Môgge Bram,
After encountering the same problem, but noticing a speed difference between different VDI's, we decided to not be greedy with the extra static delay and put in an extra 30 seconds rather than the 10 seconds that sometimes worked. We start Edge only at the beginning of the process, so some extra time here does no harm to the overall performance. If you stop and start Edge all the time, eg. after each Q-item, you want to be more picky about using longer static waits.
