Reduced it to the one level above min, but the result is hardly noticeable. > > Screen 0: minimum 320 x 200, current 2720 x 900, maximum 4096 x 4096 > Arrange the screens on top of each other, so you'll get 1440x1700 > -> How's the speed then? Wow, the difference is HUGE. There are still little slowdowns here and there compared to disabled compositing, but the workspace responsiveness is ok now. *sigh* @Martin, would you accept a hack-a-round to limit the maximum viewport to the mamximum texture size or should we "could you please stop propagating nonsense" rumble into the Mesa devs? (Maybe more polite and w/o rumbling but it actually seems this "yeah, in SW we theoretically..." junk is intended :-( On Tuesday 16 October 2012 16:37:35 you wrote:

doesn't look so much like a hack to me, to add some general checks to
SceneOpenGL to verify viewport/texture size and stop the Compositor (fallback
to XRender) with maybe a notification. Should of course also be checked upon
screen geometry change.
Should I report this bug upstream? How's the workaround going? (In reply to comment #7) > Should I report this bug upstream? no, only if you have the latest drivers installed. The report is about Mesa 8.0, while the current stable is 9.0 and the development version is 9.1. Reproduced on Mesa 9.0 https://bugs.freedesktop.org/show_bug.cgi?id=57609 FTR, we've pending review request, but introduces complex new strings. https://git.reviewboard.kde.org/r/106917/ Just FYI, I decided to report the bug upstream and got response today:
"I suspect KDE is using the advertised maximum viewport incorrectly. The OpenGL
spec requires the value be fairly large. Section 2.12.1 (Controlling the
Viewport) says:
The maximum viewport dimensions must be greater than or equal to
the larger of the visible dimensions of the display being rendered
to (if a display exists), and the largest renderbuffer image which
can be successfully created and attached to a framebuffer object
(see chapter 4).
X allows the user to create very large windows and pixmaps... even larger than
the display itself. As a result, we can't advertise a small value here and
still comply with the spec.
If KDE wants to know sizes that will be "fast," GL_MAX_RENDERBUFFER_SIZE is
likely a better metric."

Ok, many thanks for the info - that at least explains why the driver annouces to support such enormous viewports. The patch (it's in 4.11) more or less tests that (GL_MAX_TEXTURE_SIZE instead of GL_MAX_RENDERBUFFER_SIZE, but that has similar implications and too small GL_MAX_TEXTURE_SIZE adds the other obstacle that we cannot redirect eg. maximized windows) and warns about a potentially slow system for that.
