[Bug 1461569] [NEW] typing speed influences characte displayed

 

Public bug reported:

I type quite fast, with lots of non-latin unicode characters. I set up .XCompose to map <alt> <g> <a> to the Greek letter α, <alt> <g> <b> to the Greek letter β, etc. Typing the first at any speed renders letter α. But one has to noticably slow down to make sure that  <alt> <g> <b> indeed gives β, and not (now typed at full speed) "b". This is not a question of proximity between keyboard keys since <g> <f>, <g> <h>, <g> <v>, etc are as close together as <g> <b> and produce at any speed: φηϖντψ etc.
I have not checked if the bug exists for non-Greek characters.
