This issue is 100% reproducible. I have an Asus zenbook duo model UX8406CA with an Intel Core Ultra 9 285H CPU. I have the newest drivers installed according to "intel graphics software" and the Asus website (Intel Arc Graphics Driver 32.0.101.6313) and have also tried the rolling them back to the previous version, as well as installing (Intel® Graphics Driver 32.0.101.8331) which is the newest driver for the CPU that I can find on the Intel website. What is interesting about the issue is that after installing any of the 3 drivers everything works just fine. Its only after I restart the system to "finalize" the installation that the issue presents itself once again.
The issue is only present in the google play games window not the entire screen. Not sure if this issue is ultimately related to Arc drivers, some form of proprietary software or interface from Asus that enables the dual screen functionality or if this is something google play game related (it persists across all game titles)
Anyways, if someone could refer me to a resource to either trouble shoot myself or to report it to someone who could potentially get this fixed in a future driver iteration that would be awesome. Thanks to anyone who can help!
