Checked the new build (20043045) with the same script as before: 3 runs, logged out, Space every 0.3 s on a 1366x768 window.
It works. On the old build my commits stopped dead once the flame fell under about 0.47 (stuck at 194 for the last 5 s while it burned down to nothing). Now they keep landing on every press below half, and the flame climbs back: 0.30 -> 0.61 in one run, 0.21 -> 0.35 in another.
Every run still ended the same way: two bites close together took it from about 0.3 to 0 within a second. That's the second thing I mentioned (a keyboard player still burns 0 bugs: 235-299 commits per run, 0 burned), not something the fix broke. The new flame % under the mug and the "kept" number at the top make it much easier to follow what's happening.
