This fixes graphical glitches that appear next to the borders of plasma
tooltips. Additionally I added a variable that forces the effect to
drop the cache, which might be useful in the future to fix bugs.
This should fix 2 issues with the blur effect:
- It is now sufficient to have a damaged EXPANDED blurArea to trigger
an update of the caching texture.
- No glitches in cases where the taskbarthumbnail effect paints a
thumbnail of a blurred window.
CCBUG: 288568
This patch introduces some kind of damage propagation. In the old version of the blur effect
we had to repaint the whole window if sth behind the blurred area was damaged. The new texture
cache, which was introduced by the last patch, gives us the opportunity to only update parts of
blurred background texture. This means that the damaged area can only propagate with the speed
of the blurring radius per window layer.
REVIEW: 102665
This patch adds an optional texture cache to the blur effect such that damaged windows in
front of the blurred region dont trigger a repaint of the whole blurred region which pretty
often results in a avalanche repaint of nearly the whole screen.
REVIEW: 101977
This is actually a bloody hack by forcing the screen to be
repainted in each frame. This needs to be fixed in a different
way or we at least have to turn blur off by default for GLES in
the next release.
Optimize the region of the screen that's painted in each frame,
and paint the windows top-to-bottom when the damaged region doesn't
intersect any blurred areas.
The branch contains the first step in reworking the kwineffects
library. This includes:
* replacing virtuals by signals and slots
* dropping some unused methods
* remove KWin::TimeLine
More to come.
Conflicts:
kwin/workspace.cpp
QMatrix4x4 accepts data in row-major order, but returns them in
column-major order, which is not documented and because of that
I expected them to be in row-major order.
This commit fixes it and rewrites the shaders to apply the matrix
multiplications in the right order.
REVIEW: 100759
All previously existing windowAdded methods are renamed to slotWindowAdded.
EffectsHandlerImpl is connected to Workspace's clientAdded signal, which is
emitted a little bit earlier than the previous direct method call. This might
change behavior.
Another signal is added to Workspace to signal that an unmanaged is added.
Since the EffectFrames have been moved into KWin core nothing in the
Effects lib actually used Plasma. The only remaining method is moved
to core as it's not used in the Effects. The Effects itself still
link against Plasma, so nothing changes for them.
The Plasma includes in the kwineffects header seemed to pull in
quite some additional headers, so the includes in some effects have
to be adjusted (most often KConfigGroup). This should speed up the
compilation of the library and the effects.
It now uses a GLShader for GLSL shaders and pushes it using the
ShaderManager.
It does not work with the nouveau driver plus GLES, but it works
with fglrx + desktop GL 2.x, so I assume it is a driver problem here.

Adding a new AbilityUsesBlurBehind which can be set by decorations with
alpha channel to request that the background can be blurred. This improves
the situation for our completely opaque default Oxygen decoration.
This change is a behavior change in comparison to 4.5! Translucent decorations do
not get blurred by default any more.

This allows using Lanczos filter also on systems not supporting GLSL.

- Don't announce support to clients if the shader failed to compile,
or the FBO is invalid.
