Hey there!
I encountered a bug, which is extremely irritating.
As soon as you move your cursor the entire UI (except for the actual canvas) starts to flicker very slightly. This happend to me right after installing the software.
I tried the OpenGL and Direct3D acceleration methods, both seem to have that issue.
Only the “crude” software renderer does not introduce those artifacts.
I have updated my graphics driver and restarted my computer, which did not solve the problem either.
I’m running a Nvidia RTX2070, Ryzen 1800x (mentioning it because I saw you use AVX) and 48GiB of RAM.
