Mouse icon lagging behind on remote desktop

In our work environment a remote desktop system is used (Citrix).
The mouse is lagging notacibly behind when moving over the map window of QGIS. When moving over the layer tree, the processing window or the menue icons, everything is smooth again.
I think the reason for this behaviour are so-called "server-rendered-cursors". QGIS is using special mouse-icons when the mouse is positioned over the map. This results in a video transmission for every mouse-move within the remote desktop system. A "default" System cursor is rendered on the client side.

I have attached an animated GIF where a slight error happende and both mouse-pointers are visible at the same time.

I can imagine this behaviour is true for lots of different remote desktop systems.
Maybe there could be added an option to force system-mouse-icons?
