[Bug] Skipping Input Points

[jianlong-liu]

This appears to be the same issue as zsviczian/obsidian-excalidraw-plugin#1591. Nevermind, may be a different issue.

When I draw quickly (using stylus, touch, mouse, it doesn't matter), a lot of input points get skipped. I've turned on Settings > Developer Options > Pointer Location to show actual pointer trace. Red dots are the actual pointer location update events I think.

Here's a video (slowed down by factor of 10) that shows the skipping.

This is on Android 10, Cromite (Chromium fork), on a Snapdragon SDM636. Same on Firefox. Same for Snapdragon 800.
Things are fine once I move to higher-end CPUs.

Here's another website showing that it's not likely to be on the Chromium/Firefox end, as the drawn stroke follows the stylus path almost exactly.

Please let me know if I should file this somewhere else.
