I found a problem, somewhat serious. When I have a few windows open and compile OpenSolaris I am using most of my memory (3 GB) and a bit of the swap; loading the dual-core above 90%.
The problem is that I get "Window Title Bar" corruption, nowhere else on the screen is affected and there seems to be nothing crashing but it looks quite disconcerting. If I choose the corrupted window the title bar will restore itself and appear normal without any crashes. It is though "write-only" memory were being written to, and since it is never read, it never has any effect on anything (except visual appearance). Something is writing to were it is not supposed to be able to. Needless to say that a malicious program could alter the title bar (instead of writing random data) and mislead you as to the title of the window. I would not be fooled by that but it is indicative of a serious security flaw. This type of activity should not be possible. I am enclosing two screenshots: 1. Screenshot_1_OK.png -- A normal screenshot without corruption 2. Screenshot_2_BAD.png -- A corrupted title bar (pointed to with a big red arrow).

If no one finds a problem with the changes I made to the VERSION=177.80,REV=2008.11.05.10.16 I pushed out last week it will go into b103. -------------- next part -------------- A non-text attachment was scrubbed...
