We have important news on this issue.
Yesterday I reported a verified reproduction of the problem being described here (read access violation at address 8 on Windows 10) on a Dell laptop with dual Intel HD integrated + NVIDIA discrete graphics cards.
We have solved this problem on the same machine by simply updating graphics drivers to their latest versions available for Windows 10. Now we have repeated the same WBPP task 6 times without any problems. Everything has worked perfectly and PixInsight 1.8.8-2 runs absolutely stable on this laptop. So far we have repeated many stress tests with zero problems.
Here is the procedure to update your graphics drivers on Windows 10:
- From the Start menu, select Control Panel.
- On Control Panel, select System and Security.
- Select System.
- Select Advanced System Settings (left panel)
- Select the Hardware tab.
- Click on Device Manager.
- Pull down the Display adapters item.
- Right click on the item for your graphics adapter. Select Update driver.
- Click on Search automatically for updated driver software. Windows will look for new drivers online, and if new drivers exist for your graphics card, they will be downloaded and installed.
If you have several display adapters on your machine (e.g. an integrated Intel HD graphics adapter and an NVIDIA or AMD discrete card), repeat the same procedure for each of them from Device Manager.
I hope this helps. These weird access violation errors are definitely being caused by wrong or incompatible graphics drivers on Windows. They are machine-specific issues beyond our control, but at least we have managed to solve them by updating graphics drivers on the only machine where we have been able to reproduce them.
