Describe the Issue

One of my favorite presets, Phat_Eo.S. rainbow bubble_mid3-f. me dood does not render correctly in the latest version of ProjectM. I tested this on Windows using the projectM-visualizer/gst-projectm plugin. It appears to be an issue on other platforms as well, as confirmed by CodAv on Discord.

Interestingly, it renders correctly in the (long outdated) Steam frontend for ProjectM, so that rules out any fundamental issues with OpenGL.

Here is how the preset is supposed to render, as recorded in the Steam frontend on Windows:

Here is how it incorrectly renders in the latest version of ProjectM as described.
