Hi, there's a weird issue I often get when I type something inside any text-box, gedit, renaming a file in nautilus or even in my browser, what happens is I type but the last letter/s stays invisible sometimes for a few moments and sometimes until I make another action, same thing happens when I delete text too.
furthermore, another weird thing is sometimes when I right-click somewhere and move my cursor atop of the menu options, my cursor can point at one option yet, the option I was hovering on previously would be the one highlighted... :?

has anyone else encountered this issue / have a solution for this? :?:

Are you using nvidia?

I don't know if it's related, but I'm running gnome 3.10 with nvidia and I am noticing weird lag issues as well.

-gnome terminal has weird mouse scroll lag, sometimes I can't scroll all the way to the bottom
-evolution's calendar won't always respond when clicking on a day. I can click different days and the highlight will always be one click behind
-when I try to zoom in to 1:1 pixel size with large images in chromium by clicking on them, sometimes nothing happens
-dconf-editor also has weird mouse scroll lag as well
-occasional flickering/freezing issues overall with gnome-shell

There's probably more. In my very brief testing with nouveau this doesn't seem to be happening.
This problem has only popped up recently, although I don't know exactly when. Maybe during a recent driver update?

yap, I'm using Nvidia too, and I got the exact same symptoms you describe... So it's all because of nvidia you say, ha? in the words of Linus Torvalds "...so nvidia, f*ck you" haha (just kidding)
I'll start googling for info about nvidia and these lags, see if I can come up with somthing...

Thank you very much

I wonder if >=nvidia-drivers-334.* could be the culprit? I tried 337 and it has the same issue too. I didn't find much online but I didn't search for very long.

If by some miracle radeonsi got its stuff together soon, my next card might be one from team red ... I'm kind of tired of these proprietary blob issues :roll:

nvidia-drivers-331.49-r3 is the last version working without lag/delay for me.

How do you solve the problem of portage complaining about preserved 32bit egl libs with the 331 nvidia driver? Does it go away on its own?

The steps I've used:

* downgrade the nvidia-drivers to version 331.49-r3
* To fix "/usr/bin/gnome-session: error while loading shared libraries: libEGL.so.1: cannot open shared object file: No such file or directory", reinstall media-libs/mesa (because the downgrade of nvidia-drivers breaks mesa?!?)
* remove emul-linux-x86-opengl (emerge -C app-emulation/emul-linux-x86-opengl)
* reinstall emul-linux-x86-opengl (emerge -1 app-emulation/emul-linux-x86-opengl)

On my system, emul-linux-x86-opengl was the only package responsible for preserved libs.

hey, I think there's a solution to our problem, see this post: https://devtalk.nvidia.com/default/topic/690704/linux/-334-16-parts-of-the-ui-randomly-flicker-when-moving-the-mouse/post/4128101/#4128101
apparently what we need is a media-libs/clutter version 1.18 if I understood what they said correctly and this should fix the lagging...

Edit: it's on a patch to 1.16 too - "The patch is also in the 1.16 branch (not just 1.18 ) so should end up in distros soon."

This patch is already part of media-libs/clutter-1.16.4-r1 but didn't fix the issue for me :(
see http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-libs/clutter/files/clutter-1.16.4-buffer-age.patch?revision=1.1&view=markup and https://bugs.gentoo.org/show_bug.cgi?id=503560

They are talking about the clutter 'buffer age' patch, and unfortunately that is already used by the latest clutter ebuild.

edit: poncho answered before I could finish my post :wink:

Maybe this is a similar, but different, bug?

Bummer, then it didn't do no good for me too :( , because I have 1.16.4-r1 also.

alright, 2 more resources I've found are: https://devtalk.nvidia.com/default/topic/700104/linux/screen-jittering-with-334-21/
and this - https://github.com/chjj/compton/issues/181

maybe one of them has the answer, I'll check it later when I'll have more time...

Downgraded to nvidia-drivers-331.49-r3. Problem appears to be gone. I will edit this post if it occurs again.

Added to package.mask:
Code:
=x11-drivers/nvidia-drivers-334.21 #laggy, broken
=x11-drivers/nvidia-drivers-334.21-r3 #laggy, broken
=x11-drivers/nvidia-drivers-337.12 #laggy, broken
