Description
I noticed this with tst_spellchecking but it also happens with simplebrowser. Output and backtrace:

Disabling gl with --webEngineArgs --use-gl=disabled avoids the assert. Replacing the assert with an if, everything seems fine. The error codes returned are 0x502 "Invalid operation" and 0x500 "Invalid enum".
I bisected the issue to 99837d5568cceb66bb6a634dcf0fffef1473cb14 "Make ANGLE default on Linux". pvarga I wonder if you have any ideas? I may also be able to look into it further too.
