Description Prakash Punnoor 2004-05-17 14:12:52 UTC 
I guess the -fweb flag (and thus -O3) should be filtered out when gcc-3.4 is used. I think gcc3.4 has some serious issues (not the first package which misbehaves with -fweb) and I wonder why the gcc people included -fweb in -O3. In my case using -fweb, I got following erratic behaviour:

-When I click on an icon on the desktop a neighbor icon would disappear.
-The context menu shows up in purple/normal color checkboard style.

With down CFLAGs it works as it should.

Are you sure that -fweb is the cause of this problem? I have compiled the system on several computers with -fweb and I have never had such problems with it in KDE or any other de/wm.

This is from my main computer:

Comment 2 Prakash Punnoor 2004-08-22 06:54:02 UTC 
Yes, it caused the problem, as it was the only flag I changed. I could be that a newer gcc version fixed it. I haven't tried -fweb since gcc-3.4.0. Or that with a certaincombination of flags, -fweb breaks. Our flags are very different.
Comment 3 Caleb Tennis (RETIRED) gentoo-dev 2004-12-06 19:26:37 UTC 
Dunno if this is better now or not, but I'm not keen on filtering flags.
