Description gregpitta19 2012-02-07 20:39:15 UTC

Version:           unspecified (using KDE 4.8.0) 
OS:                Linux

Please have a look at the attached picture.
There is an odd glow above some box-like parts of windows. This glow some times gets corrupted and shows without transparency or with distortions.
Hovering with the mouse seems to refresh the textures.

Reproducible: Always

Steps to Reproduce:
On moving any window, specialy visible on dolphin or in system settings. Maximizing and unmaximizing the window can help visualizing.

Actual Results:  
The glow looks odd.

Expected Results:  
There should be no glow or a better placed one.

Performed on Kubuntu 11.10 x64 
Nvidia gforce 9400gt graphics card. Happens with nouveau graphics or the proprietary ones.

Using the latest version of oxygen-transparent from git.

Feel free to ask for more info that might help.

(I can't really reproduce here it seems).

Is the issue *always* here ?
Is the issue still present if you disable blur (from kwin effects) ?
Whats your graphics card ?

Also: are you running "latest" oxygen-transparent ?


Thanks for posting anyway :)

Comment 3 Hugo Pereira Da Costa 2012-02-08 12:36:42 UTC

ok. In fact, I can reproduce, and only if blur is enabled.

Comment 4 Hugo Pereira Da Costa 2012-02-08 12:51:08 UTC

cc-ing kwin, because Philip might have a word to say on it.
(it is *not* blur related, but might be opaque vs transparent region related in KWIN land)

Comment 5 gregpitta19 2012-02-08 13:10:48 UTC

Just to be sure I ran oxygen-setup.pl again. So latest build.
Issue is always there. Disabling blur makes the problem more evident, please look at the new attached screenshot.


 here is my graphics card info from lspci
01:00.0 VGA compatible controller: nVidia Corporation G96 [GeForce 9400 GT] (rev a1)
        Subsystem: XFX Pine Group Inc. Device 243a
        Kernel driver in use: nouveau
        Kernel modules: nouveau, nvidiafb

but i can confirm this bug using the proprietary drivers
