Hi, this appears to be a Chrome bug. My guess is it will be fixed in a future Chrome update.
Something specific about this SimBrief page appears to trigger it, but we don’t know what. Regardless, at the end of the day this is a bug with Chrome itself that will need to be fixed by Google.
For now, one of the following fixes from other topics might help:
- Either try changing the “ANGLE graphics backend” setting in Chrome: The screen locks - #4 by SimBrief
- Or, try using the “Small Map” option: Graphic Glitches - #4 by stevieg747
Best regards,
