Description Marc Payne 2010-07-14 18:36:21 UTC

Version:           unspecified (using KDE 4.4.4) 
OS:                Linux

The summary basically says it all. Please note that my KDE version is 4.4.92, not 4.4.4. I am not using a current snapshot, so I had to pick the most recent version in the list. :-/

Reproducible: Always

Steps to Reproduce:
Using KDE SC 4.5-rc2:
1. Enable Desktop Effects, Shadows, and Blur
2. Open Dolphin (an arbitrary example)
3. Click File
4. Move mouse over "Create New"
5. Move mouse further down in the main File menu to close the submenu

Actual Results:  
At steps 3 and 4, neither the File menu nor the submenu has a shadow. At step 5, the File menu shadow is drawn. Note that if the Blur effect is disabled, shadows are drawn correctly every time.


This is possibly related to Bug 164084 (see Bug 164084 Comment 20).

Still present in 4.4.95.

Is there any way I could have submitted this bug with correct version info? No recent beta/rc versions showed up in the dropdown lists when I submitted it...

I can confirm the exact problem here.

Using the following setup:
OpenSUSE 11.3 x86_64
nVidia 9300m using driver 256.35 
KDE 4.4.95 (KDE 4.5 >=20100723)

I was confused as to what was the culprit of this bug. Glad I found this bug report. Unfortunately, the problem doesn't seem dependent on the nVidia driver. I tried 4 different versions (195.36.15, 195.36.24, 195.36.31, and 235.35) and the problem was still present.

I also see this bug with an Intel Atom netbook (a Dell Mini 10v). However, this doesn't occure if Direct Rendering is disabled. Can anybody confirm that this is specific to Direct Rendering?

Comment 4 Marc Payne 2010-07-30 19:13:16 UTC

Bug is still present with direct rendering disabled on my end.

Comment 7 whashnez 2010-08-31 08:47:43 UTC

I have the same problem. How is this bug resolved?

Comment 8 whashnez 2010-08-31 19:22:32 UTC

Not resolved in KDE 4.5.1

Comment 9 whashnez 2011-01-27 10:30:01 UTC

Still not fixed in KDE 4.6. Why?

Comment 10 Thomas Lübking 2011-01-27 18:37:00 UTC

it's not just "fixable" but requires a complete and major redesign of the renderstack, what will happen with 4.7, please stop reporting to duplicates and use the linked one instead to avoid information fractioning, thanks.
