[otaolafranc]

Hello,
i am having issues with winapps and freeRPD nightly ubuntu.
i am having a lot of office windows that are bugged and completly freezed.
they are fully unresponsive, i actually literally dont know how to close them. and i am having small parts of my linux screen affected by, eg.:

where the blue is coming from when my winapps powerpoint window that is blocked. how can I close this office windows? before i was connecting to the windows and force unlogging and this was solving it, but now even doing this the windows stays there and the 'blue rectangles' stays. i literally need to restart the pc to make it disapear.
