yes. AFAIK, timers run in a seperate thread, but you should only call
blit operations in the thread that opened the screen. i usually use
SDL_PushEvent to generate a SDL_USEREVENT that i handle in the main
eventloop. there i read the parameters from the event.data fields, so i
know what has to be done and do the blitting stuf.

best regards …

Yep. Don’t call any SDL functions from a timer callback. Set a global flag
(or counter) to notify your main loop that the timer has expired, and then
return.
