Hey Danik, I've managed to reproduce this bug reliably.
I tested it with 16x16 tiles, as well as 32x32 tiles, and thinking it might be an even sized tile error I also tested it with 33x33 but all tile sizes successfully reproduced the bug.
I tested the following versions as reproducing the bug on Windows 10 64-bit:
- 0.4.8
- 0.4.7
- 0.4.6 32-bit
- 0.4.6 64-bit
I tested the following versions as unable to reproduce the bug on Windows 10 64-bit:
Reproduction steps:
- Make a new tiled document
- Create a new tile and create a copy rotated 180 degrees
- Paint on the left edge of the 180 degree rotated tile
Here's a gif of the bug happening with said repro steps:
