Black Pixel in the Top Left Corner of Tab Controls When the First Tab is Not Selected and Visual Effects are Set to Best Performance RRS feed

  • Question

  • In Windows 7, follow these steps:

    Computer ->

    Properties ->

    Advanced system settings ->

    Performance - Settings... ->

    Select "Adjust for best performance".

    Click Apply, but don't close Performance Options.

    Click the Advanced tab.

    Why is there a single black pixel in the top left corner of the first tab in the tab controls whenever the first tab is not selected?

  • Yes, this is only an issue with the Windows Classic theme or the Best Performance option.

  • Hi Arnav,

       I don't think this is a profile issue.

       I've wondered if this is a video driver issue.  I've tested on 3 PCs so far:
    - Macbook
    - PC with onboard Intel video
    - Virtual Machine in vmware

       It's subtle, just one pixel, but once you notice it, it'll bug you.

       Now that I try it again, I don't see the black pixel on the Performance Options dialog now, but I do see it on every tab control in every other dialog throughout the system.

  • Hi,

    I made a test in our testing enviroment, also had same pheonmenon when select "Adjust for best performance".

    The black spot would disappear when you click the first table, such as "Computer Name", "General" in your screenshot.

    In my opinion, it seems like a default design. I didn't find any document talk about this phenomenon. If there was any updates, I'll post back.

  • Hi Roger,

       Thanks for confirming this bug.  I'm not sure what you mean by "default design".  I suspect no one has noticed this because not many people use this "Adjust for best performance" mode.  Also, on a high resolution display it's hard to see.  I happened to test a system where the resolution was quite low.   On a large screen it was quite obvious.

    Thanks,

    Ben

  • Hi Roger,
       I'm sorry, I don't understand what you mean when you say you already confirmed this issue.  When did you confirm this?

       Could you be more specific about how I should provide feedback?  When I click the link you sent, I go to the Microsoft Connect Home page.  I don't know how to find this issue from there.  Is there a bug ID I should use?  I looked at my Dashboard page, and there's nothing there about this issue.  What should I do?

    Thanks,
    Ben
