Very slow SVG loading / startup on ARM (Raspberry Pi 400 @4x2.2GHz, 800MHz GPU clock)

I'm running VCV on the new Pi400 that just came out. It also runs the audio perfectly and other DAWs work without trouble, but the startup (from ramdisk, to be sure it's not disk read issues) is slow.

Note: might be worth recompiling with "-mcpu=cortex-a72 -mfloat-abi=hard -mfpu=neon-fp-armv8 -mneon-for-64bits". I'm trying it now and will share my results.

sorry, somehow i did not notice this issue when it was opened ... i think the reason for the slowness is the gpu of the rpi which cannot really compete with desktop gpus for the many gpu operations vcvrack seems to require to draw the initial screen. it is even worse on slower gpus like mali450. i guess recompiling for a72 will not give much - maybe 2-5% cpu i would guess if anything at all.
