Hello,

I also get the exactly same behaviour sometimes, never knew how to fix it.

I'll take a look as soon as I can.

Do you also use the FMX platform?

No, i use the VCL version.

While I try to find the cause of this issue please check the following :

• If your app don't use a 'cache' directory set GlobalCEFApp.DisableGPUCache to TRUE.
• Don't modify VCL properties inside TChromium events because most of those events are executed in a CEF thread and some VCL properties are not thread safe. It's recommended that you use 'PostMessage' to send a message to the main form to modify the VCL in the main application thread.
• If you see that error then close your app and delete the cache contents if you use a 'cache'.
• Some properties are considered 'experimental' by Google like : GlobalCEFApp.SmoothScrolling, GlobalCEFApp.SitePerProcess, GlobalCEFApp.FastUnload and TChromium.HyperlinkAuditing. Using these properties might cause problems.
• If your app doesn't need Flash, set GlobalCEFApp.FlashEnabled to FALSE.

I just updated CEF4Delphi and removed the GlobalCEFApp.DisableGPUCache property.
Now GlobalCEFApp disables the GPU cache automatically if there's no 'cache' directory.

I've created an issue in GitHub for this bug :
