Here, very old project but demonstrates the problem well as it uses a lot of objects.

EDIT: the code is in the Step event of sonic_player object

Also occurs in HTML5. Basically causes events to glitch out and does not work as intended even with less objects.

OK the project given does not run in GM:Studio and has lots of errors - until I get another example that works and is simple (not a whole game) I'm not going to address this one.

I am going to add a new one for you when I get back home.

Attached a quick example (not sure if the way I used is a proper way to test lag)

Using your sample...

// CASE 1
// Windows: ON 60 FPS, OFF 8
// Android: ON 20 FPS, OFF 2 (Galaxy S2)
// HTML5: ON 60 FPS, OFF 60 (Chrome, no WebGL)

instance_activate_all();
instance_deactivate_region(view_xview[0], view_yview[0], view_wview[0], view_hview[0], false, true);

// CASE 2
// Windows: ON 60 FPS
// Android: ON 30 FPS and no screen flicker or crash
// HTML5: ON 60 FPS

instance_deactivate_all(true);
instance_activate_region(view_xview[0], view_yview[0], view_wview[0], view_hview[0], true);

Case 2 is the winner, but these numbers don't seem bad at all for the amount of instances and work being done. HTML5 clearly doesn't active instances off-screen regardless of if you manually specify it. I also didn't get a crash on my phone, but a low-end phone may well have issues with this test.

I think HTML5 is just very fast (actually faster than Windows)
Yes, it seems the crash & flicker no longer occurs. Also the FPS looks improved, although the example does lag on my Android Phone but the device itself a bit underpowered.
Maybe this has been already looked into?

Possibly - if there was a consistent crash, then I assume something was changed somewhere along the line ;)

Glad it's working okay now anyway. Those numbers I saw were perfectly good (excellent, even) for the amount of work being done and assets in use at once, so Resolving as No Change Required. But perhaps was fixed...
