Resizing canvas label creates memory leak (especially with big font sizes)
Versions tested: v0.9.1 happens and latest nightly build 885a64577
I was debugging one of my patches that used multiple canvas labels as moving UI elements and started having slow performance/crashes seemingly randomly. I narrowed it down to when I was resizing canvas labels, and my RAM kept getting filled over time until I closed the plugdata instance.
This becomes more apparent when resizing to big label sizes (reaches like almost 1-2GB/s of RAM usage until it maxes out, smaller fonts usually fill around 0.2-1MB/s ish) It starts off stable, then within like 10 ish seconds, starts filling up quickly, regardless of font used.
I've included an example patch below to demonstrate:
[!WARNING] Be careful not to resize too quickly or too much or RAM will get filled really fast lol :D
