Red Hat Bugzilla – Bug 1255750
Since upgrade to 6.7, xfreerdp has trouble keeping window refreshed
Last modified: 2015-08-25 10:01:42 EDT
Created attachment 1065592 [details] Xorg.0.log for graphics hardware/driver identification Description of problem: Ever since upgrading to RHEL6.7, the xfreerdp session I have open to a Windows Server 2008 R2 terminal server does not always redraw the screen when transitioning back to it from another virtual desktop. Windows from the virtual desktop I was on previously will remain drawn over the top of the xfreerdp window. Moving the xfreerdp window off screen and back, or minimising the applications _within_ the window and then maximising them again redraws things correctly (not the taskbar as that doesn't get redrawn in this instance), but this shouldn't be necessary.

I've never seen this with GNOME. X server should maintain the window contents. Expose events should be generated if the window contents have been lost from some reason. Xfreerdp listen expose events and redraw the window contents if needed. Backing store for the xfreerdp window is set to always, which means that X server should maintain the window contents also when the window is unmapped. Apparently the window contents is lost from some reason and the window is not redrawn. Please follow the steps and provide logs to be sure that the expose events are generated properly: 1/ first connect to the server with xfreerdp as usual 2/ run following command and select xfreerdp window, xwininfo will generate info about the xfreerdp window "xwininfo -all | tee xwininfo.log" 3/ then run following command and select xfreerdp window again, xev will be monitoring all the xevents "xev -id $(xwininfo | grep id: | cut -d ' ' -f 4) | tee xev.log" 4/ reproduce the issue and then stop xev using ctrl+c 5/ please attach xwininfo.log and xev.log
OK, logs attached. Please note that I had to flip between KDE virtual desktops a bunch of times before a Konsole was drawn over the top of my xfreerdp window when flipping back to the virtual desktop with it on. As a result the xev.log has a lot of stuff you won't care about in it before the end. Sorry about that.
Created attachment 1066793 [details] xwininfo log file for the xfreerdp window
Created attachment 1066794 [details] xev log, logged as requested
Thanks for the logs. Backing-store is set to "Always" for xfreerdp window as per xwininfo.log. It means that X server should maintain the window content also when the window is unmapped. There isn't any expose event in the xev.log. So it seems the window content was corrupted in the backing store somehow and unfortunately no expose event was generated. This is probably bug in X server. It seems to me to be duplicate of Bug 1250105. I wanted to ask you to test this with disabled backing store as suggested in the mentioned bug, but the system doesn't boot correctly with disabled backing store for me... So marking as a duplicate, because freerdp was not updated in RHEL 6.7 and the symptoms seems to match the mentioned bug... *** This bug has been marked as a duplicate of bug 1250105 ***
