Revert "Fix NTP thumbnail generation"

Revert of "Fix NTP thumbnail generation" and "Fix local variable init problem detected by the memory sanitizer."

This reverts commit d77a3639f04f83a5c5cf47d88dbac2f0d4345ea5 and 99fea0b98aa55336753da894d80d2a3f2bc66171.

The thumbnail generation fix apparently causes runaway CPU use in certain cases and needs to be reverted.
