I found a bug. If, while in tab view, an image is large enough that clicking the view button would click the image underneath, then clicking to switch from tab to board can mess up the image's position on the board. This only happens if the user moves the mouse during the click on the view button, even if just one pixel.
Thanks for reporting! Not sure if I understand it correctly... please, could you open an issue on https://github.com/raylibtech/rtools to review it?
