Hello,
I have pushed a commit on the tree which I think should fix your issue.
I believe that some engines don't set the alpha channel on the game surface properly as this surface is not intended to be transparent.
Therefore, I hack the alpha channel to make it opaque.
Even when fiddling with the code selecting the screen pixel format, I haven't been able to reproduce the issue using QfG2 remake on my Android devices so I can't be completely sure it will work.
The next daily build will get the fix.
That's a pity you can't sideload our debug APK as it would speed the debugging process.
Did you try to look at the following instructions?

Please note that as I don't know ChromeOS I don't really know the implications of applying these.
The ChromeOS octopus device seems to be an x86_64 device so make sure to select the proper APK on the Buildbot.
