SDL_ShowOpenFileDialog slower with larger window about sdl HOT 4 CLOSED

Can you try with testdialog? I've tried with that on my device, and it consistently takes about 1 second to open, regardless of whether the window is maximized or 50x50.

You'll need to open test/testdialog.c and change the SDL_CreateWindowAndRenderer line (86) to have the arguments ("testdialog", 640, 480, SDL_WINDOW_RESIZABLE, &w, &r), then run from the build directory:

cmake -DSDL_TESTS=ON ..
make
.\test\testdialog.exe

from sdl.

After some quick testing, it does appear like the testdialog example opens consistently regardless of window size. I noticed testdialog uses a while loop while my application and the ravbug example uses the newer SDL_AppIterate. Could this be somehow related to the file dialog delay? I'll do some more research on my end.

Maybe rendering the bigger window puts more strain on your computer which slows down the opening of the file dialog? Note that the testdialog limits the frame rate using SDL_Delay(100) so that might be something you want to try in your application if you're not doing that already.

After more testing on several different systems, I believe this is a windows issue or issue with my laptop. Other computers open the file dialog consistently.
