Using aaronp's sdl_test I got the following results on arch using gnome3:
After seeing the cursor pressing and holding "down arrow",
approximately 5 seconds later single press of space while still holding "down arrow"
and keeping "down arrow" pressed for around 5 seconds and quitting with esc while still holding it down.
default key repeat settings:
Pressed: down - 2619
Pressed: space - 7804
Released: space - 7976
Released: down - 9478
Released: down - 10980
Released: down - 12481
disabled gnome3 key repeat (universal access settings):
Pressed: down - 2169
Released: down - 3670
Released: down - 5171
Released: down - 6673
Pressed: space - 7303
Released: space - 7430
Released: down - 8931
Released: down - 10433
Released: down - 11935
So using no repeat actually releases the key even before pressing space , I am confused...
But seeing this now I remembered using Linux Multimedia Studio music software (also using SDL1)
The piano roll can be played with the keyboard, and when holding a note (with enabled key repeat), it will release by its own and start repeating the key.
The repeats while holding a note there are:
8000ms / 13000ms / 13400ms / 14500ms / 16300ms
This will continue in a seemingly random fashion
But turning off key repeat in gnome3 works ok for LMMS , but not for dosbox.
Could this be a broken key repeat detection ?
Have to check how this is handled using wayland and its XWayland compatibility layer.
EDIT: Scratch that, on my system my dosbox build under wayland gets almost NO KEYS, as in 1 keystroke of 100... so better not explore this any further 😊
