[R92 - R93] Platform behavior collision bug?

After upgrading to r92 I noticed a "stuck on the wall" effect jumping to the left against a solid block when the charachter is falling along the wall and is some pixel above the floor. On Chrome and Firefox it's a subtle stop during the fall that resets gravity effects on charachter, on mobile devices the charachter stucks in middle air until it's moved to the right breaking the whole gameplay.

This doesn't happen always, seems to be totally random.

All is working perfectly when you jump to the right.

Here's the capx

To explain what I mean I added a sound that plays everytime the falling speed is below a threesold. You'll notice that jumping on the left against a wall the sound sometimes is played two times.

I have the same problem on r95, trying to figure out why. Any explanation for this?

Oh... I forgot this...

Currently I use this workaround.

player has wall on the left

player is not on floor

-->

player set x to player.x + 1

If you use an invisible box as player you can adjust via events the position of the main charachter to avoid any noticeable gap between the sprite and the wall.

It's probably related to these two:

Knifegrinder - I can't reproduce this any more in r98 - I think it may have been fixed with some of the other bugs. Can you confirm?

Ashley, this is the same issue I'm having with objects with many point to define his collision boxes.

Some boxes dropped on the mountain will hit the floor and will go through it ignoring the collision box completely on the highlight area.

TELLES0808 - that looks like a different issue to the one posted here actually. Could you make a separate thread for it?
