Easy enough to check if you're hitting the floor after our scaling, with a custom DPI, the computation is as follows:
12. * (SCREEN_WIDTH/600. + 90/127.) / 2.
If that falls below 12, yep, you're hitting the floor

.
(Note that SCREEN_WIDTH may not technically be the width, I'm assuming Portrait, here. In practice, it's the dimension of the smaller side of the screen. IIRC, somewhere around 1080 on a Clara/Glo).
Assuming I remembered the right screen size, I'm getting something like 15 with the crappy calculator I have on hand, so you might want to try lowering the floor check in my first link, as that's easy enough to do

.
If that does the job, that's harmless enough to be a general purpose fix

.
(As would lowering CRe's floor be, while we're there, it's just harder to quickly test, as it requires a rebuild).
