Quicktime FILL screen - MacBook pro 2017 TB intel graphics bug

I have a MBP 13" without Touchbar and an integrated Intel 640 Graphics - Quicktime shows exactly the same Problem here as soon as the Video expands to lap over the edge of the Screen (i.e. 4k Videos when choosing to play them native or if Screen Fill is chosen for 16:9 Videos).

I made a Screenshot of this, the Video will start to play fine, but as soon as the Video Controls fade out scrambles the Screen with black-white lines. It is also not possible to take a Screenshot of it, as the Screenshoot will always look fine. I'll take a Picture with the Phone one time.

I have found out that this only affects Quicktime when playing H.264 Videos. Tried with MPEG-4 was no Problem. I was in Contact with Apple Support regarding this, so far they are clueless and asked me to perform NVRAM, SMC Reset - to no help until now.

I somehow suspect a Problem with Hardware H.264 Decoding by the Intel Graphics Chip in conjunction with Quicktime.

By the Way the Image returns to normal als soon as any Notification, Decals, Controlls, TopBar etc are displayed. The Error only shows up if the play video Image is shown.

I have the same problem with Quicktime in Macbook 2017 (with Intel Graphics 615 and High Sierra).

According to my opinion this problem occurs from video driver into Quicktime for MacOS. I tested, in the same Macbook, VLC media player in MacOS, Super Player Lite in MacOS and Quicktime in Windows (via Boot Camp) and and there is not any problem!!. So, Apple ought to solve the problem either with a new driver for Intel Graphics for MacOS or with update for Quicktime.

Not Sure why this platform is here I have the same problem . but I have discovered over the years that asking Apple anything relating to software or hardware problems is about as helpful as asking my basset hound

Hi, I have a similar problem after update from 10.12 to 10.13.2

My Mac:

MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)

with Intel Iris Plus Graphics 640 1536 MB

See you.

Same issue on my Mac

Macbook Pro 13 TouchBar and TouchID.

I've done all tests that apple support advisors told me to do.

reset NVRAM and SMC

reinstall MacOS...

None of them worked.
