Hi, some of my colleagues are experiencing an error where the chart won’t render and there was an error message: WebGL context lost. It had been happening regularly.
They were using Windows 10 Dell laptop with Intel Core i7 10810U 1.1Ghz and Intel UHD graphics 1Gb memory, running Crome 131.

Hello Edvin, we have some suggestions of what to check and try.
-
We’ve seen issues with Intel UHD integrated graphics before. There were known driver issues, which have been reported to Intel. At this point, updating the graphics driver usually helps.
So, the first step when you encounter this problem is to identify whether the issue is reproducible on a specific hardware/environment.
Try switching to a different GPU via settings if possible.
As mentioned above, try updating the graphics driver. -
Since WebGL context loss is a system-wise event it affects all programs using it simultaneously and can cause the GPU crash overall. Thus, check whether another process or library may be causing the crash.
-
Another reason we suspect might be causing this is high memory consumption.
Again, check the hardware capabilities, general memory consumption, and memory consumption within the browser tab. Here, you can use some tools for debugging, including the Task Manager and various browser Dev Tools.
Then, if you suspect the issue is caused by SciChart-related logic, you can use the MemoryDebugHelper provided by the lib to verify that. You can find more info in the Memory Management Cheat Sheet document (References and other content in the folder might also be useful). -
If you’re having trouble with this or find a bug, please send us the information you gathered. Then, we can investigate or suggest further actions.
