            Bug ID: 89374
           Summary: Firefox smooth scrolling isn't smooth
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: minor
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: sunweb@hotmail.ru

Kubuntu 14.04 x64, HD5770

glxinfo |grep Open
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD JUNIPER
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.2
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 10.3.2
OpenGL shading language version string: 1.30
OpenGL context flags: (none)

Firefox has an option of smooth scrolling(Preferences -> General -> Use smooth
scrolling). However it doesn't work on OSS drivers for my card. It does work on
Intel ones and closed source though.

Please attach the /var/log/Xorg.0.log file and the output of dmesg.

Does Option "AccelMethod" "glamor" in xorg.conf help?

Hi, here're the files https://bugs.freedesktop.org/show_bug.cgi?id=89275

I don't have xorg.conf and installing glamor package didn't work out because of
Ubuntu bug.

No need to install any additional packages, just put something like this in
/etc/X11/xorg.conf:

Section "Device"
        Identifier "Device0"
        Driver  "radeon"
        Option  "AccelMethod" "glamor"
EndSection

No difference. Also i may took a wrong wording. Smooth scrolling can be enabled
but its not as smooth as it should be. Also i've recentley saw ff on windows
machine and it also has some animation when you press on Open Menu and far
better animation when you're going to/out Tab Groups. Those animations don't
exist on my machine. Maybe thats Firefox issue after all.

Did you verify in /var/log/Xorg.0.log that glamor was enabled?

Ok, i just tried glamor on a bigger sites and i do see a difference, it is
smoother that the default option but it is nowhere as smooth as supposed to be.
On top of that, enabling glamor breaks my experiance with Gwenview, it simply
hangs, shows first picture and hangs. I also have to enable vsync in KDE
settings to prevent tearing and set it to "full scene repaints" any other
option give no result and "re-use screen content" simply kills any desktop
experiance to that point you can't use menus, drag windows(that are already
open) or open new ones, awful flickering etc.

Now that i think of it glamor is the only option for newer GPUs. Is it that bad
for them as well or is it just bad experience with the old ones?

That would need to be tracked in a separate report, with detailed information
about the versions of gwenview/KDE/Qt and how to reproduce it.

With current xf86-video-ati Git master, you can enable DRI3 with Option "DRI3"
in xorg.conf. Then "Re-use screen content" should work well. The breakage
without that sounds like a kwin issue.

I always experience some troubles using the latest versions so i stay ou of it.
But i wouldn't want to use this option because on EXA i have no tearing even
with Vsync = none.

About this non smooth scrolling issue. I feel like i am the only one here. If
you do not have this problem than what card are you using and is it working as
smooth as on Windows?

Not using Windows or smooth scrolling myself, I'm just not sure how smooth it's
supposed to be. Don't worry, I'm not arguing there's no problem, just making
suggestions that might improve your experience.

I've tried it in a notebook that has both intel and amd graphics. On intel
smooth scrolling even at heavy sites works really good.
A bit offtopic. How do i use amd gpu in such notebook and are you planing to
add some gui to switch between gpus and choose what programms to run with which
gpu?
