With this hot fix, it's less than a second as expected. Menus pop also, like they should. Microsoft says the fix is NOT in yet. It will be in the next OS and might be made available no warranty in an insider's update. At least some of our customers say applying the fix makes no difference. A co-worker has experienced the same issue and the same KB update fixed him also we both have the same PC.
However, no driver updates have occurred since then. So did that driver cause my problem? But then how did the problem go away on my PC? I don't expect any answers, just thinking out loud. Customers say that once things slow down, rebooting fixes the issue for a while.
MS says GetPixel exacerbates the problem as they are allocating memory for one pixel at a time. My guess is that memory may be getting fragmented over time as it sounded like calling GetPixel in a loop used to result in the same memory being allocated, freed and allocated but is now getting new memory for each call.
So perhaps a reboot helped? Or the GetPixel call isn't the root of your issues. When you are frozen, do you debug break and find yourself in the low level get pixel code? Since it is "fixed", this is not as simple to do. However, if I find the time, I could roll back and possibly duplicate the problem and do what you said.
I think the memory fragmentation is the cause. We are seeing the load of our app getting "slower". The problem is indeed with the Fall Creators Update. After investigating it it's turned out the Magnifier is the one to blame for performance issue. Even if you don't use it it is still responsible. As a simple manual workaround just disable bitmap smoothing in its options.
Unfortunately so far there is no known method for disabling it for a specific application. It is also a known issue to Microsoft already, hopefully they will address it soon. Alexander, I have an open case with MS. GetPixel is not the only affected API but it definitely exacerbates the issue due to it constantly allocating memory for a single pixel.
There is no "work around" that will solve that issue. I suspect Magnifier is just like many other programs in that it too is making lots of calls to GetPixel.
Microsoft has a fix for the next release. They might make it available for people in the insiders program. I have filed out the necessary forms to request a hot fix. I asked again today if the hot fix will be made available no reply yet. You then pass it in subsequent calls, e.
Try using copy of Bitmap from file. FromFile function on some files returns "slow" image, but its copy will draw faster. I had the same problem and I found the best solution.

You're right, there isn't a Graphics. DrawBrush method. I've never tried reusing the same brush after modifying the corresponding bitmap, so I don't know if you have to recreate it or not.
I've used TextureBrush with a half transparent image. The image was completely rotten. Show 1 more comment. You have a screen of x resolution?
If not, you should draw only the visible part of the image, it would be much faster Steam is a slow pile of bleep, I see its border shadow and then some time later I see the application draw its own GUI. Driver issues maybe?
Firefox with D2D enabled is blazing fast on my systems. No stray boxes, no slow GUI, nada. It's fast across the board, and my system is just a healthy "mid-range" setup, nothing fancy.
It is an interesting tidbit, but at the end of the day, it doesn't make a difference for most users. I've never had to switch between controls so rapidly, and the window lag has no effect on functionality.
Honestly I would have never noticed if it wasn't for this video, I never find myself rapidly resizing windows all the time. I get the white screen too on Windows 7 - However I don't tend to resize windows much, They're usually always maximised or a size that I don't need to resize.

This is obvious and well known. Microsoft simply hasn't bothered hiding this for some bloody reason. I am also not sure that D2D fixes the issue Aethec Posted November 2, MS Bob 11 Posted November 3, Posted November 3, Max Norris Posted November 3, ToneKnee Posted November 3, Joey S Posted November 3, There's another aspect you're not taking into account.

Installing Windows So here's some insight, I have to install Windows 7 in an old machine since that's what my friend prefers. Given the myriad of updates there are for that OS right now I was wondering what would be the quickest route to a fully updated system, in essence, installing the less updates possible.
So far, starting from the refreshed image of SP1 I've done the following: - KB For the updated root certificates.
