Yes, it is about "deoptimalisation" - but we can remove most of the CreateHBMP to save some time Wink

.
On all my computers I have 32bit color depth, but I tried to change it to 16bit at "the bad" computer and the problem disappeared. Strange...
I've attached the .iml file from the real application, it's the "Exclamation" symbol that causes the problem.
In attached "ImageWin32.cpp" on line 309 I've put the only two operations for if(GetKind() == IMAGE_MASK) statement to have the problem still appearing. If I remove the ::Delete operation (keeping only the ::CreateCompatibleBitmap), the problem disappears.

Really weird as you have basically removed painting for masked images...

Well, this code exists mostly unchanged for more than 7 years - and I see nothing wrong with it. You also seem to be unable to 'isolate' the issue in testcase. Given these fact I would say that there might be some nasty bug in your app that somehow generates the problem... Or maybe the computer is broken, even such things happen...
