Hi Garden Dwarf,

On my home computer I was able to run your application and I also sometimes received the same error message with the crash. Sometimes it crashes without an error but I also had a few cases where it successfully resized. I found a comment somewhere that said on Windows platforms you need to reinitialize some things after the resize. The fact that I could resize a few times makes me think it isn't a driver issue but some kind of memory allocation or math error due to resizing.

I created a simpler program to demonstrate this error by adding the resizeable option to one of the examples that come with the SDL module. I'm planning to try it tonight on Linux to see what happens.

This isn't my tested version but should be close. 

#modified version of SDL-2.548/examples/SDLx/app.pl
use SDL::Event;
use SDLx::App;

my $app = SDLx::App->new(
    title  => "Lines",
    width  => 640,
    height => 480,
    resizeable >'on',
);



sub draw_lines { $app->draw_line( [ 0, 0 ], [ rand( $app->w ), rand( $
+app->h ) ], 0xFFFFFFFF ); $app->update(); }

sub event_handle { 
    my $event = shift;
    my $app = shift;
    $app->stop if ( $event->type == SDL_QUIT ); 
    
    if($event->type==SDL_VIDEORESIZE){
        $app->resize($event->resize_w,$event->resize_h);
    }

}

$app->add_event_handler( \&event_handle );
$app->add_show_handler( \&draw_lines );

$app->run();
