Description Dirk 2010-12-15 09:21:41 UTC
Version:           SVN (using Devel) 
OS:                Linux

After the moving of the windows, the windows get suddenly invisible.
On Kwin in 4.5 it works as expected.

Debian Squeeze with the radeon free drivers with version 1:6.13.1-2+squeeze1.
The graphic card is a 512 MB ATI Mobility RADEON HD 4570.
Trunk is used, yesterday updated and compiled.

Maybe also the glxinfo is useful:

Screenshot of Effect

How the effect looks like.
Comment 2 Thomas Lübking 2010-12-15 12:48:18 UTC
please try to set the scale method to "smooth" instead of "accurate"
Comment 3 Dirk 2010-12-16 15:50:36 UTC
Thanks,
with scale method "smooth" there are no problems, everything works as expected.
Comment 4 Thomas Lübking 2010-12-17 00:32:43 UTC
Do you use some sort of window translucency (ARGB support in Bespin/QtCurve/Oxygen or fixed window opacity < 100%) or are the invisible windows supposed to be "just default opaque windows"
Comment 5 Dirk 2010-12-17 14:32:46 UTC
I use the default settings and didn't change the window opacity option.
And every window gets invisible after the movement.
Comment 6 Martin Flöser 2010-12-18 13:37:46 UTC
what about thumbnails in the tooltips?
Comment 7 Dirk 2010-12-19 16:05:51 UTC
The thumbnails are only white with accurate, while with smooth there is a picture shown.
Also for Desktop Grid something simmilar is happening, with accurate the whole window (expect the + and - at the bottom) gets black, while with smooth everything works.
Everything seems to work.
Comment 8 Thomas Lübking 2010-12-19 16:14:54 UTC
this is most likely #258439 - if you compile yourself you can test one of the patches attached there, but it may also be that shader support in your driver is just _really_ broken :-(
Comment 9 Dirk 2010-12-19 18:58:37 UTC
Its not fixed. It looks now different thow..
The windows are not any longer black at the end of the movement, they are now gray and the active one is invisible.
Are there other ways to test the shader support?

It seems that also the Blur effect cannot be entabled.. =(
Comment 10 Thomas Lübking 2010-12-19 20:23:11 UTC
I think lanczos & blur are currently the only effects supporting ARB shader - everthing else would use glsl (apparently not supported by the driver) or no shaders at all.

I fear you'll have to wait for a driver update, sorry :-(

If XRender is ok for you and you want some sort of blurring, have a look here:

Comment 11 Dirk 2010-12-21 14:44:29 UTC
It seems that the driver is the newest version (6.13.1).
If also others have the same problem, it might be a good idea to default the scale method to "smooth" on the free radeon driver.

Thanks for your help and work on kwin.
Comment 12 Martin Flöser 2010-12-30 18:17:13 UTC
altogether, it's a driver bug :-(
Comment 13 Fredrik Höglund 2011-01-13 09:01:32 UTC
Please note that you're using an outdated version of Mesa. The current release is 7.10.

The R600 driver was in an early stage of development in Mesa 7.7, and this problem should not be reproducible in more recent versions.

xf86-video-ati which you were referring to is the 2D driver.
