Any ideas what might be the cause?

[magreenblatt]

Does the problem reproduce with cefclient? What is the full set of command-line flags they you're passing?

[ronag]

No problem with the cefclient.

Options used are:

Code: Select all

off-screen-rendering-enabled
disable-gpu
enable-begin-frame-scheduling
