[Bug 1460062] Re: Scrollback with Shift-PageUp Shift-PageDown does not refresh screen
I'm pretty sure by now that this issue has been video-driver or compositor related. After upgrading to Wily and a different NVidea driver, it seems to have disappeared. Prior to that, I noticed lag for several other operations, like scolling in browser windows, with the result being unconsistent until one moved around enough with the mouse or did other operations that might fill some small pipeline to the point of flushing. So I'm pretty sure that this bug is not actually GNOME terminal related. It may just be that GNOME terminal got more economical with its redrawing/refresh and thus made it more likely to leave the uncompletely flushing rendering pipeline in a state where the visual feedback was not-yet-helpful. Sorry for the noise. ** Changed in: gnome-terminal (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1460062 Title: Scrollback with Shift-PageUp Shift-PageDown does not refresh screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1460062/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

There are some known glitches with highlighting, but I'm not sure I
understand your situation.
Let's start with the simplest one: no highlighting, just
Shift+Page{Up,Down}. How does the bug occur exactly? How can I reproduce
it? (I'm using these keys all the time and never had a problem, except
for https://bugzilla.gnome.org/show_bug.cgi?id=160127).

Basically, when using Shift+Page{Up,Down}, the display tends to lack one
keypress behind. So if you change direction, it appears as if the first
move is in the wrong direction.
It may well be relevant that I am using Cinnamon as my desktop. Maybe
it is less generous with expose or other events.
It also helps if there is no other action on the screen (no other
window). My terminal window is always vertically maximized and there
are several terminal tabs in it. It's not perfectly reproducible, but
doing S-PageUp and S-PageDown several times in a row is rather likely to
trigger it. Sometimes the cursor blinking causes a refresh, so it's
also more likely with the cursor off-screen.

[Bug 1460062] Re: Scrollback with Shift-PageUp Shift-PageDown does not refresh screen
Sounds really interesting. Any chance of this being the same as https://bugzilla.gnome.org/show_bug.cgi?id=730763 ? Could also indeed be an issue related to Cinnamon. Can you try to reproduce under a different WM? Can you download vte-0.38.3, compile with ./configure --enable-debug; make and launch with ./src/vte-2.91, does it also misbehave? If so, start with VTE_DEBUG=all ./src/vte-2.91, do you see the entire window flashing up in red for each Shift+PageXx keypress, and is the result still buggy? Is there output produced between the Shift+PageXx keypresses, or is it irrelevant? ** Bug watch added: GNOME Bug Tracker #730763 https://bugzilla.gnome.org/show_bug.cgi?id=730763 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1460062 Title: Scrollback with Shift-PageUp Shift-PageDown does not refresh screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1460062/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
