I spotted this as well, it actually only happens on my macbook, not my Windows machine. @duianto what type of graphics card do you have?

duianto commented 3 years ago

GeForce GTX 550 Ti

Curious that it doesn't happen on my Windows box, it even happens on my mac with really small images so it's not hitting memory limits. Will keep looking...

Actually managed to repro on my Windows machine, it's just a different/worse result on mac 🤔

Verified this is not due to VS Code's Electron 11->12 update

It only happens on images of a certain size, it happens on 800x600 but not 32x32

That was a challenge lol, the bug ended up being tiled textures which are only used for bigger images were using the wrong dimensions and being stretched. Thanks for reporting!
