Input gets eaten during continuous rewinding (was: during right-click scrolling)

[Simon]

CE 1.0.1
NL 12.14 and other versions from years ago.
Wine 10.6

• Start a level.
• If it's a small level, zoom in until you can scroll.
• Scroll with the hold-to-scroll feature. E.g., map this to the right mouse button in NL's options, then scroll by holding the right mouse button.
• While you hold-to-scroll, press a skill hotkey to select a different skill.

Practically everything is wrong in this OP, see my next post instead.

Observed: You have a ~50 % chance to select the new skill. Otherwise, the skill key has no effect and the old skill remains selected. (The hold-to-scroll will always continue to scroll correctly, whether the new skill selects or not.)

Expected instead: The new skill gets selected for certain. (And the hold-to-scroll will always continue to scroll.)

Very strange. I'm not currently at my laptop so I can't test this immediately. Has anyone with a Windows machine noticed this?

Best guess is that it's something to do with hotkey priority, I'll take a look at it soon.

Sorry, this one is on me, I confused practically everything in OP. I should have consulted my notes.

The correct repro is:

• Play any level.
• Fast-forward 5 minutes.
• Press and hold the 1-physics-update-rewind hotkey.
• During this rewinding,
  • start to right-click scroll (press and hold),
  • or zoom with the wheel (rotate several notches),
  • or select skills by hotkey.

Observed for right-click scrolling:

• You have a 50 % chance that the starting click to right-click scroll fails. If this click fails, the subsequent holding also fails, guaranteed. You have to release right mouse button and re-click-and-hold.
  
• Rewinding continues correctly, it doesn't depend on the scrolling's failure or success.
  

Observed for zooming with the wheel:

• For each of the mouse wheel notches individually, you have a 50 % chance that it will fail.
  
• Rewinding continues correctly, it doesn't depend on the zoom's failure or success.
  

Observed for skill selection by hotkey:

• The skill has a 50 % chance to get selected.
  
• Rewinding stops. It doesn't depend on the skill selection's failure or success; it always stops.
  

Expected: Rewinding always continues, and the second input always succeeds.

The 50 % probability is on smaller levels: Automaton Maintenance, or Save Our Souls. On big, laggy levels, the probability of failing increases. I fail to right-click scroll with 70 % or 80 % on Space Program 10,000 BC.

The probability of failure increases during in-game times such as x:x9, x:x8, x:x7. It's lower immediately after an internal 10-second savestate around x:x1, x:x2.


I'll copy this into OP in a few days.

As WillLem says: Who can repro this on Windows?
