Short description of error
If you activate the Redraw Timer operator (Anim Play)
It just endlessly loops and there is no way to stop it except to force quit in the OS.

Exact steps for others to reproduce the error
open any file (new)
Press F3 to search (or whatever your search button is)
type "Redraw Timer" > Enter
Then chose the Anim Play option.

Boom - I hope you wanted to watch that animation play forever haha

Are you sure it's infinite?
Redraw Timer is an operator used to benchmark UI.
By default it runs all timeline frames 10 times. (See rB92145d59)
Also by default the timeout is 60 seconds.
We could use WM_cursor_time instead of WM_cursor_wait.
But that is another topic and is not a Bug Tracker scope.

You are correct - if you let it run it does loop 10 times which is about 44 seconds.
Which does seems like infinity.

Maybe some type of visual feedback and/or a cancel function would suffice.

can confirm on this one. on windows 10 + nvidea Gpu
it should run 10 times.
with or without an animation the result is the same on second run it hangs with nothing obvious wrong.
cant confirm its infinite loop only something strange is going on
