Thank you for the reply,
1. How often do you get that error message?
I mostly get this error message when changing the resolution on Elsword.
2. Does it happen only when playing Elsword?
It seems like it, I've tried 4 games to see if the error occurs, none of them gave an error message.
3. Are you able to change the screen resolution without getting the error message?
Only on the 4 games I've tested. Elsword shows this error message most of the time (I've also noticed that when you change the resolution a lot of times, it gives the igfxTray error message more frequently.)
4. Does this happen with customized drivers from your computer manufacturer?
No, it doesn't happen from the customized drivers from my computer manufacter AND the generic drivers from Intel (every update prior to 18.104.22.16822)
Hmm, as of now I've received another error message about this but it didn't come from the game, the error messaged popped up from another program (Speccy, with the exact same message.)
So far, I've received 4 exact error messages from 4 different programs. Also, it doesn't happen just by changing resolutions but also by performing Alt+Tab while playing a game (happens at random times.)
It's quite likely that the Intel driver is causing this (this error have been occuring for the past few days after updating the graphics card), what I've noticed though is when I run a demanding program and try to open up a third-party program, the error message pops up.
This also happens when I try to open up the Intel Graphics GUI. Giving out the exact error message but with a different process name (the Intel GUI.)
I'll try my best to identify what is the main cause of this.
