SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and now iOS Charting & Android Chart Components
Got a wierd issue. My client is installing my application (built with Scichart) and everything works fine, except on the laptop of this one particular guy, where the zoom does a wierd thing. It zooms the axes, but the graph is not moving. I’m quite sure there is nothing wrong with my application as it works everywhere else, but can any of you think of anything that I should check on this guys machine? I am at a complete blank here…
Thanks for helping me out….
We actually have a reproduction of this bug that occurs on some computers – without using SciChart.dll. It appears to be an issue with some Intel Graphics drivers and WriteableBitmap / .NET4/4.5.
Please download the attached solution and run it on computers where you see problems. Click on the main form. If all is working, you should see a coloured square drawn, which changes colour on each click. However, in systems with this problem, the form will be blank.
What we believe is happening is the WriteableBitmap once locked/unlocked once is not allowing any further updates. The same code works perfectly well on many other machines and the only other workaround is to disable hardware rendering for the WPF process on systems that exhibit this problem.
We have contacted Microsoft and Intel to see if any will take ownership of the fix. In the meantime, as a workaround you will have to disable WPF hardware rendering for the process.
So I might have a solution for this. The machine in question was restarted in safe-mode and then the application was started and worked fine. So it had to be some kind of driver issue right? So there was an intel-driver for an onboard graphics card that was the cause of the whole issue. This driver was uninstalled and again it was working fine. Downloaded and installed a new updated driver and now everything works fine.
So anyone else having this issue, try running the application in safe-mode. If the zoom works fine in safe-mode, chances are you may have the same buggy driver installed. Check for updates for that graphics driver.
Hope this helps
