Windows 10: 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?

Which is better Nokia C5-03 or 500?

A GPU helps you render 2D and 3D games smoothly in your phone. It is like graphics card on a computer... When you have a GPU, it enables better rendering of high end games in your phone... A Nokia 500 has a 2D GPU with HW accelerated Open VG1.1 support...
So as chanchan says Nokia 500 is way better than a C5-03...

 

graphic accelerator !!!!

There's nothing you can do as a phone user to make games run faster/smoother. The developers might be able to optimize their code better for that particular device/hardware, so at most, you can complain to the developers of such apps/games.



The Nokia 500 does have "2D Graphics HW Accelerator with OpenVG 1.1 support", but as mentioned, no 3D hardware acceleration is mentioned in the device specs:

So, any 3D graphics (e.g., using OpenGL ES) is going to be done with a software rendering library, and there the processor speed, memory speed, and memory interface (bus) are limiting factors, as well as the quality/performance of the software libary, and
how the developer is doing things.

 

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! *Huh
