 3. It is recommended to use the high contrast theme for the best result or at lest any dark theme.
 My suggestion is to enable the high contrast theme

+## Super important!
+To get high performance, go to: File->Settings 
+And make sure you enabled "Enable GPU Acceleration (For NVIDIA CUDA Enabled GPUs only)"

+This option will work only for NVIDIA GPUs 
+
+Otherwise, you may have to reduce the screen resolution to maximum 1920x1080 because the effect may not work fast enough without GPU Acceleration.
+
+If you think that you can optimize the performance for CPU (without GPU Acceleration), feel free to design a better algorithm here:

+Replace this function with your faster algorithm and submit PR.
+The function is responsible for detecting the texts(or any shapes...) so that when the opacity applied, the opacity will not include the texts.
+
+The result will look like this

+That the texts/shapes have no opacity at all but everything around it have opacity.
