Hi,

I am using a relatively new version of freerdp: 2.0.0-rc2 (2d0439b). 

I have to use an older version of the Linux kernel (3.2.102) and X11 (version 
1.11.4) because the old thin client has problems with the openchrome driver 
with newer versions of X11. The driver cannot find a connected monitor via I2C

The server is Windows Server 2016.

With the same freerdp (version 2.0.0-rc2 (2d0439b)) I have no problems on 
environments with current X11 (for example X11 1.16.2) regarding rdpgfx 
channel. 

Is it possible that the dropouts are caused by the X11 server or by changes in 
event handling in freerdp for X11?

regards

Michael

Hi,

which version of freerdp do you use? Might be related to a bug already fixed if 
it is an older one.

The server OS and settings would also be very relevant. /gfx was introduced 
with windows 8 and nearly each version since has introduced a new mode (avc420, 
avc444, ...)

By default avc444 is not turned on or some line idle setting server side might 
kick in.

Armin


P.s. Would suggest to not use the async options as they have been buggy and 
only work properly with certain preconditions applied.
