Apps flicker and crash

[rocket2nfinity]

I've had this issue on several versions of ubports (reflashed) and it's still there on the latest stable branch (v3). This may very well be a hardware problem, but i've yet to have any issues with mobian.

Can this be related to a high dram clock speed or would that have effected more than an isolated app? #noob

I'm thinking it's a clock speed issue. Mine has been very buggy out of the box. Went to an earlier pre-ota build it works fine. I thought maybe the device was defective until then. Current OTA 3 is so buggy, it will only boot one out of a dozen tries. There is a fix for Mobian and the other distros, but it doesn't work with UBPorts for some reason.  So still searching for a solution for that.
