I am working on a series of variable pixel fonts as part of my diploma thesis. The application is lagging a lot in the process. I realize that this is probably related to the fact that there are quite a few pixels in each character, and that the pixel itself is not exactly a simple shape and contains many points. I wanted to ask for the purposes of my work whether you have tested what contributes more to causing this behavior, or whether it is a combination of the above factors. Or whether it could be another factor, such as the age of the device or something similar.
I completely understand if this problem has no solution, I wanted to push the application to its limits, I am just interested in it for the purpose of my research.
Thanks a lot.
