Wayland client - screen flashing on every update

[grawity]

Starting with commit 3d77496, when the wlfreerdp client is connected to Windows 10 (from within gnome-shell 43.2), every screen update causes the display to flash/switch between what appears to be two different display buffers ("current" and "a few moments ago"). For example, if I open the Start menu on the remote host, with every mouse movement the display flashes between the menu being open and it being still closed (or open with some chunks missing).

This is a new issue in FreeRDP git; it doesn't happen with wlfreerdp 2.8.x or 2.9.x. (But on the other hand, it's exactly the same commit that fixes the memory leak I reported in #8399...)

will most likely not be fixed.
wayland client has been deprecated with 3.0 and will be replaced by sdl-client

NOTE: pull requests are, of course, always welcome.

I had this on the Wayland client. If you want native wayland use the SDL client with the following variable:

SDL_VIDEODRIVER=wayland,x11

The SDL client, for some reason, isn't working for me at the moment though

@rlees85 which issues do you have with sdl-client? (discuss this better in a new issue or our matrix chat)

[rlees85]

I've raised it here: #9354
I'm having a good play with it this morning so I will update it with any more information I find and will post some screenshots on Matrix as well.

thanks,

xrdp,rdesktop was flickering,
sdl-rdp was laggy,
export SDL_VIDEODRIVER=wayland | sdl-rdp works best
