Diagnostic information for Intel desktop

Output from "qdbus org.kde.kwin /KWin supportInformation"for a second machine (desktop based on motherboard DQ77KB with Intel integrated graphics) exhibiting the same chrome menu problem as for the Lenovo Y510p laptop that had the output in comment #2

nevermind. try:

kwriteconfig --file kwinrc --group Compositing --key GLStrictBinding true
qdbus org.kde.kwin /KWin reconfigure
qdbus org.kde.kwin /KWin toggleCompositing
qdbus org.kde.kwin /KWin toggleCompositing

Yes!  I have tried your four commands on one laptop, and this does fix it both immediately after running the 4 commands as user, as well as after logging out and back in again.

I will try the same on the other machines and also check that the problem remains fixed after reboot, and I will report back shortly.

Many thanks for your help with this.

I have tested the same four commands as per comment #5 on a second machine, and the problem is fixed there also, including after logout/relogin.  I have also rebooted the first machine and the problem has also remained fixed there too.

Does this fix require the same commands to be run for each user on each machine or will this be fixed in a future package update?

Actually I thought we already shipped a fix, but apparently only for 5.x, not 
for 4.11: 
http://quickgit.kde.org/?p=kwin.git&a=commit&h=e8241313fc979aefafc8c2a0207570d6394f1580

we should backport that one, shouldn't we?

from the review comments, i thought "we" had - and yes, "we" should ;-)
should "we"? should "i"?

Hello,

I still get this issue with Chrome menus on Plasma 5/Frameworks 5 if I use EGL instead of GLX...

Intel Haswell Graphics

Should I make a new bug?

What's the output of
   qdbus org.kde.KWin /KWin supportInformation | grep -iE '(strict|version)'

You need commit e8241313fc979aefafc8c2a0207570d6394f1580

Ah, it's because of

    if (isMesaDriver() && platformInterface == EglPlatformInterface) {
        // According to the reference implementation in
        // mesa/demos/src/egl/opengles1/texture_from_pixmap
        // the mesa egl implementation does not require a strict binding (so far).
        m_looseBinding = true;
    }

Please add

GLStrictBinding=false

to the [Compositing] group in ~/.config/kwinrc, restart KWin ("kwin_x11 --replace &") and ensure that this "fixes" it.

Thanks but it didn't work for me: -

Ok, leaving aside the logic error on my side (the initial setting was supposed to be "corrrect", are you sure this is egl?) this is a different bug.

Please file a new one and attach the complete output of "qdbus org.kde.KWin /KWin supportInformation" and a screenshot or video of the issue.

Well, I set EGL in the compositing KCM. It seems to have no glitches apart from this Chrome issue whereas with GLX I sometimes get some weird flickering in certain parts of the screen.

How can I prove I'm running EGL otherwise? Looking at the /.config/kwinrc it actually says: -

[Compositing]
AnimationSpeed=3
Backend=OpenGL
Enabled=true
GLColorCorrection=false
GLCore=true
GLPlatformInterface=egl
GLPreferBufferSwap=a
GLStrictBinding=false
GLTextureFilter=2
HiddenPreviews=5
OpenGLIsUnsafe=false
UnredirectFullscreen=false
XRenderSmoothScale=false

I had seen such a problem the other day and can pass a patch along

I'm still seeing this problem in plasma 5.3.2 with Chrome 45, and the same effect is also apparent on the launcher widget.

Like perrantrevan, you're on EGL (and I assume the problem only manifests there)

a) please open a new bug (it seems to be totally unrelated to this since...)
b) try to enforce strict binding in ~/.config/kwinrc, [Compositing] group: GLStrictBinding=true
    and restart "kwin_x11 --replace &"
    (....but from perrantrevan's comments, this won't help)

@Martin, you suggested a patch for this (specific EGL issue) in comment #18?

yep, found a patch from that date which seems fitting

Author: Martin Gräßlin <mgraesslin@kde.org>

    Also disable loose binding on egl
    
    See e8241313fc979aefafc8c2a0207570d6394f1580.

See comment #13 - perrantrevan initially had strict binding enabled, so I'm not sure that covers whatever he (and maybe Martin vE) sees :-(

Indeed, I am on EGL and can confirm the problems disappear when switching to GLX. So that's a good work-around for me (I don't exactly know the difference, but thought EGL was the "future" technology, hence my choice for EGL).
I tried the suggested GLStrictBinding=true fix, but that didn't help (under EGL).

So, yes I think it's an EGL issue and for now I'm good using GLX. Do you still need me to open a new issue? If there's anything you want me to test (except compiling a new plasma-workspace because I don't have the resources to do that right now) please feel free to ask.

Video or at least screenshot would be cool (to have an idea what this looks like)
Also you could try to set the tearing prevention to "none", resp. "full scene repaints" to see whether this might be caused by re-using an old buffer or insufficient update regions.

Since this is a completely different bug, we should rather not "pollute" this one with it.

I opened Bug #352427.
As written there: none, or full-screen repaint don't help.
