Can someone add this one to the list and bug-tracker, please (renaming local variable of a sprite causes name changes in scripts of other sprites):

http://scratch.mit.edu/discuss/topic/5781/

It can be pretty disastrous in some cases…

Thanks.


BTW, @Exhelah, the ghost vector paint glitch (shown in original post list as “Ghosted vector costumes showing non-uniformities”) has a simple workaround you can use for now: just set the brightness of the costume to -1 before applying the ghost. (This one is in the bug-tracker, number 549, so it'll hopefully get sorted at some point.)

I made a game using vector images, and it super lags because of it, people told me to use Firefox or something that isn't chrome which reduced the lag a lot than the time I used chrome, but I must play small screen for the game to be playable, this never happened to my bitmap games, is it a bug? Because I would love scratch if the problem were to be resolved!

Thanks!

The dissapearing text bug is still in scratch D:

That is probably the most series bug in the project editor.

@Fishismyfish123:

There are certain things you should try to avoid when using costumes - for example, don't switch costume unless you have to (i.e. only when it's not already on the costume you want), because scratch re-rasterises every time you do. Taking a quick look at your project, you're doing that a lot, and I think that is the major source of your lag problem.

Along similar lines (though I didn't see you doing this in your project), if you change brightness/ghost/color effect, or you change its size, you should make sure you only do it if you know it's not already how you want it (i.e. keep track of what setting it has already, if you have to).

See here for some discussion:

For other lag problems, take a look at the following forum topics, and see if anything in there matches your experience…

I've got a small project I put together which shows off some of this lag under different situations - with keyboard and mouse events:
http://scratch.mit.edu/projects/10125047/

Just to clarify what I wrote above, I suspect the reason it's more laggy in Chrome is probably a combination of the above effects.

You're doing lots of costume switches (even though it often doesn't actually change which costume it is), so it's under heavy load because of the re-rasterising. In such a load situation, the keyboard (and sometimes mouse) lag problem shows up more keenly - in particular, with Chrome.

So I wouldn't be surprised if sorting out your costume switching makes Chrome not suffer so much.

Are you finding that it's when you press (and hold) keys that you're getting the lag problem most? If so, I reckon above is why.

Hope that helps!

I go into paint on vector and I can’t open my backpack. I tried restarting mi iPad, didn’t work, I tried opening a new tab, didn’t work, it’s so annoying it worked last time tho
