[kde-freebsd] Display Problems in 4.8.3 on FreeBSD 8.3 stable

[David Booth]

Hi:

I updated to 4.8.3 this weekend and now have display rendering issues 
in windows for KDE applications.

The first issue seems to be a vertical offset issue.  All of the KDE 
windows seem to have their content offset to the top.  For example, if 
I open a web page in Konqueror, the top two inches of the page 
disappear under the title bar and there is a corresponding gray 
rectangle at the bottom of the page with no content.  I see the same 
thing in other KDE windows.  For example, if I open a Konsole window, 
the window contents are shifted upwards so the top two lines of text 
are not visible and there is a gray rectangle at the bottom of the 
window.  Also, if I use the mouse to select a line of text, the 
highlighted line of text is two lines above where the mouse cursor is 
located.  Similar behavior is seen with buttons.  Generally, in order 
to select a button, I have to place the mouse cursor a half-inch or so 
below it.

The second issue seems to be redraw issue.  If I minimize a Konqueror 
window and then expand it again, it come back with just an empty gray 
background and no content.  If I decrease the size of a Konsole 
window, the old full-size window remains visible in the background.

Another issue is that some KDE windows come up blank when opened (such 
as the Application Launcher).  If I move the mouse around in the blank 
window, items will appear and disappear as the mouse moves over them 
and off of them.  With this behavior, I cannot change any of the 
system settings as the window is unusable. 

I have tried various values for kern.ipc.shmni and kern.ipc.shmseg up 
to 4096 and it seems to make no difference.

Non-KDE applications such as Firefox, Opera, Gimp, Thunderbird, 
GoogleEarth etc. do not have these problems.  They work fine.

The video card is an Nvidia FX 2700M (G94GL).  I  have tried with the 
native Nvidia driver as well with the NV driver and VESA.  The 
behavior is the same for all

This all seems very similar to the behavior that KDEgames had in 
4.7.4, but the rest of the KDE windows worked well there.

I see occasional errors on the console from which KDE was started such 
as:

QNativeImage: Unable to attach to shared memory segment

and

kpat(2724)/KSharedDataChache: Unabel to find an appropriate lock to 
guard the shared cache.  This *should* be essentially impossible. :(
kpat(2724)/KSharedDataCache: Unable to perform initial setup, this 
system probably does not really support process-shared pthreads or 
semaphores, even though it claims otherwise.
kpat(2724)/KSharedDataChache:  Unable to unmap shared memory segment 
0x80e200000

Does anybody have any suggestions to try to fix this? Do I have a 
configuration issue somewhere?

Environment is 8.3 stable AMD64 updated as of 5/26/2012.  Ports all up 
to date as of 5/26/12. X.org X Server 1.10.6

Hardware:  Intel T9600 processor with 4GB ram, Nvidia FX 2700M (G94GL) 
video card.

This hardware/Xorg configuration worked fine with 4.7.4 except for 
KDEgames as mentioned above.


Thanks for your help.
