Hi, I didn't check all your calculations, but did you noticed that when the dialog is resize you do the FitMat* twice? When MatA is resized, you compute both, then MatC is also resized and you compute both again.
I think it would more interesting to set the size only of the respective metrix inside resizematrix_cb. And if the size is growing this means that you are setting a combination of sizes that are larger than the current size. Must recheck those calculations. Try inspecting the new sizes and comparing them to the calculated size.
