Version: 4.7 (using KDE 4.7.1)
OS: Linux
When selecting raster as the graphics rendering system through kcm-qt-
graphicssystem (or by appending "export QT_GRAPHICSSYSTEM=raster" on
.bashrc) kwin appears malformed. This was not happening on versions
before kde 4.7.
Reproducible: Always
Steps to Reproduce:
Append "export QT_GRAPHICSSYSTEM=raster" on a profile file (~/.bashrc or /etc/profile) log into KDE and turn on desktop effects.
Actual Results:
kwin appears malformed
Expected Results:
kwin should appear normally as it does with Xrender.

Xrender for compositing works as intended
This is a snapshot when Xrender is selected as the rendering backend for
Desktop Effects (not the graphics sunsystem).
kwin does not appear malformed.

I can only recommend to not use KWin with raster and your hardware. It
is extremely old and it is unlikely that we can ever reproduce issues on

I will soon receive an r300 to try to fix some r300 related issues which
might also improve the situation on r200. If that won't help, we won't
be able to support your card. I'm sorry.

very simple: support for raster is a new feature in KWin 4.7. Before
KWin was enforcing native.

*cough* ... "on that chip/driver"
Eg. the nvidia driver incredibly sucked (past - it's better now) at pixmap allocation but can do XRender matrix transformations or alpha blending nearly as fast as on OpenGL - *way* faster than the cpu.
The issue is likely that xrender isn't implemented by that driver at all and the generic sw implementation of XRender is... "suboptimal" ;-)

!!! This will be overridden by the next kde-workspace package upgrade and you'll have an outdated kwin.bin while kwin will be the elf binary.
Ie., you'll have to repeat the entire procedure. !!!

I get this error when typing the command, are you sure you wrote it
correctly?
I dont know if Arch users are aware of this, but when I asked them why
KDE looks so slow they suggested me to use raster and I did, which it
looks faster that time with KDE 4.6, I dont really understand whats the
difference now, except of the new kwin's support for raster.

thanks, that was fast :-)
Relevant information:
* GL_ARB_texture_non_power_of_two not supported
* GL_TEXTURE_RECTANGLE_ARB supported
Based on that I'm confident that the fix I'm working on might fix this
issue, too.

Generate texture coordinates for limited NPOT support
Fixes rendering issues with R300 and similar GPUs. If the texture
uses GL_TEXTURE_RECTANGLE_ARB as target the tex coordinates need
to be adjusted. This at least fixes missing text on EffectFrames
with graphicssystem native on R300. Hopefully more issues are

yes - or course you can omit the raster graphicssystem altogether and
use the video memory instead of the system RAM - no idea who would
compile/set raster as default anyway ...

The setting is -if- encoded in Qt or set by a global environment variable.
While it actually can be a significant performance boost, this heavily relies on the GPU/driver/CPU combination and the application code (the more QPainter::drawImage() calls you find, the better are you done with the raster engine).
In return applications & widgets being rather tied to an X11 environment
can even segfault on this graphicsssystem (the Qt event translator
widget & it's usage seems prone to this)
The setting in kwin's advanced compositing setup is btw. not affected by
this - XRender means XRender and OpenGL means OpenGL. Only the decoraion
and plasma element (buttons, boxes) painting does really align to the
graphicssystem.

Also Notice: that remaining minor glitches are expectable due to the layout of the texture and resulting interpolation errors.

And here is the kubuntu 11.10 package patched with the current patch,

here's a better patch but currently i need to figure out why
a) the shadow texture is packed this way in the first place
b) the texture format isn't set to GL_TEXTURE_RECTANGLE_ARB (in case NPOT isn't supported but that format is)
Also see updates on bug 293325

also fixes oxygen-theme related video artifacts, but results in new video glitches (at least in the firefox), and frequent random system hangs (requiring a reboot) when child popups are started. So this patch is not usable.
Neither of these patches fixes the graphicssystem=raster artifacts.

Since the difference is only where in the texture what pixmap is deposited:
- How do you determine this?
- sure it requires a *reboot*? Suspending the compositor isn't sufficient? (shift+alt+f12)
Can you still switch to VT1 (ctrl+alt+f1, first ensure that this works in general and wasn't deactivated by your distro)
If you can move to VT1 during such "hang", please log in there, gdb attach to the kwin process and fetch a backtrace. You can pipe gdb through tee to dump the output. Please attach that.

Its pretty much a 'hard hang': cannot switch vts, cannot logout, can't
even remotely log in, no response to keynboard, etc; simply have to
powerdown..

Forgive me, but not sure what you mean here w/GL_TEXTURE_RECTANGLE_ARB
.. is this and env var ?

Fair enough, btw. what GPU are we talking about and does it actually have
glxinfo | grep GL_ARB_texture_rectangle
(In reply to comment #57)
> Forgive me, but not sure what you mean here w/GL_TEXTURE_RECTANGLE_ARB .. is

No, a texture format that doesn't require textures to be POT (power of two dimensions) but predates and is rather inferior to the "legal" NPOT textures.
If supported and used when loading the texture, this would skip the prescaling to POT dimensions (thus those offset issues) but also break eg. clamping.
Since it's however also used by the GL_texture_from_pixmap conversion,
that's actually no argument (as least as that the format is probably
slower than POT textures)
If you've support i'll pass you another patch attempt.

Yea! Great work. This is the fix:
https://bugs.kde.org/attachment.cgi?id=68664
So, the patch
http://commits.kde.org/kde-workspace/4281fd09be344bfa99b0450eae384b49b55db152
plus
https://bugs.kde.org/attachment.cgi?id=68664
appears to fix everything. I also tried with and without both changes in
Comment #53, and they have no obvious effect.
At this point, I think I'll do a clean build with the two patches above
and only post back here if any issues occur later
Thanks very very much for this work.

I guess you mean the hangs I mentioned.. nope, with the above two patches I haven't been able to reproduce them. Looks really good; have done a clean build and tested on the following GPUs which had the problems:
VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]
VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility
FireGL 9000] (rev 02)
VGA compatible controller: Intel Corporation 82865G Integrated Graphics
Controller (rev 02)
VGA compatible controller: Intel Corporation 82852/855GM Integrated
Graphics Device (rev 02)
and all look really good now. So, at least for me (and hopefully
everyone) it appears to be fully fixed.
If you have any updated/improved versions of the patch(es), or
additional patches for similar/other issues feel free to send 'em my
way, and, time permitting, I can pretty quickly test them as I build all
sw on my systems and keep trees around to save time.

Basically - you described the procedure right. I do not know the
particulars of rpm building, though.
