Hi there, starting from last upgrade I have for both PMDG 737 and A320 the following: the instruments light flickering heavily until I start the first engine. After that, everithings return to run perfectly.
Someone else had the same problem?
thanks for the help.
Hi @PVISkinny,
Welcome back to the MSFS Forums! I’ve moved your post from the Bug Reporting Hub to the Aircraft & Systems category in our User Support Hub, as you have stated your issue is related to 3rd party products and is not a bug in the default simulator. Please ensure to check which category may be the best for your questions in the future, and if you are filing a Bug Report for the base simulator, please don’t delete the provided template!
Thanks

Do you have a video of this by any chance? I was flying the 737 all day yesterday across multiple legs and did not have any flickering. I’d wager it’s something strange on your side, but would like to see exactly what you’re seeing.
The fact that you’re seeing this issue across two separate aircraft suggests it may be a graphics issue on your system.
What do you mean by “last upgrade”?
