Bug#848134: xfce4-terminal: Weird buffering problem
A very similar (perhaps the same, perhaps not) problem has been reported at https://unix.stackexchange.com/q/509773 . As per the answer given there, it might be a video card driver problem recently fixed at https://bugs.freedesktop.org/show_bug.cgi?id=110214 .
Bug#848134: xfce4-terminal: Weird buffering problem
VTE (libvte-2.91-0) recently received lots of changes to its drawing component. There were bugfixes around rendering, especially in non-compositing mode [1] and many simplifications and cleanups [2] released in version 0.56; followed by even more simplifications and cleanups [3] for version 0.58. I'm pretty certain that 0.58, if not 0.56 already, fixes the issue.

Yes, I did something similar: I created a new user and it didn't show the problem, so I started to diff every configuration file between old and new user. After a lot of tests, this is the change in .config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml which finally fixed my problem: --- a/xfwm4.xml +++ b/xfwm4.xml @@ -65,7 +65,7 @@ - + Why I had "false" instead of "true"? I don't know. Maybe "false" was the default in some old Xfce4 version? I don't know. What's this use_compositing thing and why it affects text buffering? No idea. Anyway: To reproduce, please set "use_compositing" to "false" and just try this simple "ping-simulation" script: #!/bin/sh for i in `seq 100`; do echo "64 bytes from 130.206.193.115 (130.206.193.115): icmp_seq=$i ttl=56 time=24.3 ms" sleep 1 done If you see two lines every two seconds, that's what it happens to me. Thanks.

Honestly no idea. Could be related to the terminal config, your shell, your network interface (for the ping stuff), the kernel… At that point, anything, really. > > I can understand your feeling that my description is not complete, > because it's not enough for you to reproduce the problem, but OTOH I > don't really know what kind of detail may be relevant. > > Could this be related to #733722? I honestly don't think so, especially since it has apparently been fixed in vte3. Regards, -- Yves-Alexis signature.asc Description: This is a digitally signed message part

severity 848134 normal thanks [ Downgrading because this seems not to happen to everybody ] On Sun, Dec 18, 2016 at 01:55:39PM +0100, Yves-Alexis Perez wrote: > On Sun, 2016-12-18 at 13:44 +0100, Santiago Vila wrote: > > What I did was this: > > > > ping google.com > > > > and I got two lines of output every two seconds. > > > > This was in my computer at work, so I can't reproduce it right now. > > Because you don't have xfce4-terminal at home or because it's just not > reproducible either? The latter. I have xfce4-terminal at home, but I can't reproduce the issue here. > > I'm not sure how to answer about your question regarding configuration. > > Do you mean the full contents of ".config/xfce4/terminal"? > > [ I usually only change the font size and the colors, so I don't think > > how that would be relevant ]. > > Maybe not, but something specific on your box makes it happen. So: What kind of thing may make this to happen? I can understand your feeling that my description is not complete, because it's not enough for you to reproduce the problem, but OTOH I don't really know what kind of detail may be relevant. Could this be related to #733722? Thanks.

What I did was this: ping google.com and I got two lines of output every two seconds. This was in my computer at work, so I can't reproduce it right now. I'm not sure how to answer about your question regarding configuration. Do you mean the full contents of ".config/xfce4/terminal"? [ I usually only change the font size and the colors, so I don't think how that would be relevant ]. I fully agree that this is very weird, but when it did happen, it happened with xfce4-terminal and it did not happen with gnome-terminal or in the Linux virtual consoles. That's the reason I reported this against xfce4-terminal. Thanks.

Bug#848134: xfce4-terminal: Weird buffering problem
Package: xfce4-terminal Version: 0.8.1-1 Severity: important Dear maintainer: Using xfce4-terminal, I do this: ping google.com and instead of one line per second, as usual, I get two lines every two seconds. The problem also happens when I ssh to some server and do cat some-text-file.txt Very often, but not always, I see most of the file and then it hangs. If I press Enter then I see the remaining of the file and the result of pressing Enter after the cat command. I'm using "important" here because this is very very annoying. In fact it's so annoying that I'm switching to gnome-terminal (where the problem does not happen) until it's fixed. Please feel free to ask me any kind of test to perform in case you could not reproduce this in your system. Thanks.
