Do you have your tileset images in the correctly-named folder, as specified in the plugin parameters?
This plugin was primarily designed as a way for people to port their Ace games into MV and be able to work on them without sourcing new images, so it was really intended for use (and tested) with tile sizes smaller than MV's 48x48. You may be able to go a LITTLE bigger, but not much (I tried 72x72 and that's still too big).
The solution used by the person who previously had a similar issue might work in your situation too - instead of using such large tiles, he used 48x48 tiles without this plugin, and grabbed a zoom script.
What was the previous version you had? MV 1.3 completely changed the way drawing is handled, by upgrading to the new version of Pixi and using WebGL. I didn't have to make any changes to the plugin to make it compatible with 1.3.*
I've only made some very minor changes between this version and the last, and only one of them would have anything to do with the way things are drawn. If you want, you can try and undo this change (it's just a matter of commenting out those two lines in the Tilemap class), but you risk re-introducing the choppiness that that mod removed:
The issue seems to be caused by the changes in 1.3 - so if you MUST have the larger tiles and don't want to use regular-sized tiles with a zoom script, the only option I can see is to revert to 1.2 and use the newest version of the plugin. The only changes are the choppiness fix, allowing you to give it a different file name, and listing the resources used so they'll be included when you deploy your project. You won't need to revert to the previous version of the plugin.
Personally I'd look at an option with smaller tiles.
Check out this post then, higher up in the thread:
If that works, it would be a much better solution for you.
can i change 32x32 tiles to 48x48? i dont know how.... i want to buy the horror bundle, but first i have to make sure, or i cant use it
The purpose of this plugin was to allow people to use the resources from their VX Ace projects in MV without having to resize them. So that's a 32x32 tile size. Someone tested with 16x16 and that worked well, too. It wasn't designed with larger tiles than MV in mind (anything bigger than 48x48), I didn't even consider that people might want to use larger tiles when I wrote it, and it's already been discovered that some tile sizes are just too big - not because of the plugin, but because of the limitations of the engine (not sure if it's an MV thing or a Pixi thing).
So in short, for smaller than 48x48, you should be okay, for larger, don't expect it to work.
