I once had a similar problem due to bad interaction with the clipboard
manager. Do you use klipboard? What happens if you disable it?

Just a guess...

Typing in LyX extremely slow / produced high X server load

[Rainer Dorsch]

Hello,

I noticed that typing in LyX sometimes becomes incredibly slow (it takes 
approximately 1s per character). top shows in these cases a very high Xserver 
load:

  PID USER  PR  NI  VIRT  RES  SHR S %CPU %MEMTIME+  COMMAND
   
 5310 root  20   0  460m 450m  12m R   95 11.3  49:24.01 Xorg   
   
  706 root  20   0 000 R   17  0.0 181:51.20 flush-8:0  
   
 7223 rdorsch   20   0  291m  81m  33m S4  2.0  19:50.77 kwin   
   
20076 rdorsch   20   0  136m  70m  21m S3  1.8   3:07.05 lyx   

Restarting LyX solves the problem for a while. I think the problem comes 
suddenly, but so far I could not find out what exactly triggers the problem. 

I think the problem might be caused by LyX, but CPU cycles are actually spend 
in the X server. Is there anything I can do to track down the problem?

Thanks,
Rainer

I see the same, but only if the LaTeX PREVIEW window is open and it is
set to show the complete text, not just the current paragraph.

How about your condition? Using preview?

No, I do not.

I think LyX was a victim not the root cause, I found in my Xorg.0.log file:

[mi] EQ overflowing. The server is probably stuck in an infinite loop.

Not sure what is causing that, but that does not look goodI disabled kwin

that I do not see the EQ overflowing often anymore.

No, I do not.

I think LyX was a victim not the root cause, I found in my Xorg.0.log file:

[mi] EQ overflowing. The server is probably stuck in an infinite loop.

Backtrace:
0: /usr/bin/X (xorg_backtrace+0x3b) [0x80d91fb]
1: /usr/bin/X (mieqEnqueue+0x1ab) [0x80d7cbb]
2: /usr/bin/X (xf86PostMotionEventP+0xd2) [0x80b8322]
3: /usr/lib/xorg/modules/input/evdev_drv.so (0xb5281000+0x4831) [0xb5285831]
4: /usr/lib/xorg/modules/input/evdev_drv.so (0xb5281000+0x4b26) [0xb5285b26]

7: (vdso) (__kernel_sigreturn+0x0) [0xb776b400]

Not sure what is causing that, but that does not look goodI disabled kwin 
effects (KDE4) now, hoping that this removes enough stress from the X server 
that I do not see the EQ overflowing often anymore.

Thanks,
Rainer
