Slight occasional stutter when playing `Poland can into Space` on the Pinephone running GloDroid v0.7.5 #203

I spent some time playing my favorite open-source Android game Poland can into Space on my Pinephone (UBports Community Edition with 2GB RAM) running GloDroid v0.7.5.

The good news is that it runs smoothly most of the time, with proper graphics, sound and vibration support.

However, I did notice that the game occasionally stutters, ever so briefly. This affects gameplay, since it's quite a fast-paced game, and the phone very briefly stops responding and missing user input during those stutters, which is enough to lose the game, even if happens just for a fraction of a second.

I know, I know, a casual game like this doesn't seem like the most important use case, but games are a good way to stress-test graphics, animation, sound, input lag, etc.

I'm not 100% sure, but I don't recall experiencing these stutters when I tried out the same game on v0.7.4. If it would be useful in helping to troubleshoot this, I guess I could downgrade the phone to v0.7.4 and try playing the game on that version again. Let me know if you'd like me to test that more thoroughly.

I've noticed logd write to serial console blocks all interrupt for 30-50mS if logdscheduled on CPU0.

Can you try disabling serial console and check if that fixes the issue?

adb root && adb shell "echo 3 > /proc/sys/kernel/printk"

The latest releases should have a silent serial console after a successful boot. If this is still an issue, please open another issue HERE.
