    Hardware-accelerated 2D apps rendering issue while restore/maximize


    Hello!

    Starting with Preview builds and continuing to 10240, I have a strange problem of 2D graphics rendering. I use Visual Studio 2015, that is a great example of the issue. When I switch between Maximized and Normal window states, usually (~50%) I end up with something like this:

    The same can be found with custom WPF applications:

    Mouse events (hover, click) over the blank/unfinished areas force those particular regions (panels, buttons) to redraw.

    When I disable "hardware graphics acceleration" in Visual Studio, its rendering becomes correct even without program restart.

    The problem appears on both external (HDMI connected) and internal displays (including HDMI cable disconnected).

    I have DELL Inspiron 7348 laptop with Intel Core i7 5500U CPU and HD Graphics 5500.
    Although the system is installed from scratch, I have installed all the manufacturer provided drivers.

    Yesterday I've run Dell's hardware diagnostics utilities. It tested the video card for about half an hour with different scenarios, like shaders visualization, some kind of transformations, stress tests and so on. The picture was always correct, and the tool has diagnosed no errors.

    Windows logs does also contain no graphics-dedicated errors.


    Could you give me any checkup/audit/diagnose suggestions?

    Go to the Intel website and run the Intel Driver Update utility. Intel may have newer video drivers for your embedded video than what's on the Dell site.

    Thank you for the response!

    I updated my Intel HD Graphics driver from 10.18.15.4240 (from DELL) to 10.18.15.4256 (from Intel).
    And it actually solved the problem. Pretty simple yet straightforward!
