Bug Report
Spark Profile: Google Drive (can't upload directly to GitHub, spark profiler was not able to upload to a perma link)
Note: Tested in creative for spark profile, however issue occurs on both Creative and Survival, and on both Singleplayer and Multiplayer (since NEI is Client side). This profile was gathered mostly by sitting in the inventory doing nothing, occasionally scrolling all uncollapsed pages.
I ran a different profile where I opened the inventory, uncollapsed all items, scrolled through all pages, then sat letting the profiler run for a few minutes, before opening the GUI and scrolling through all pages again.
I did not notice a decrease in memory usage from NEI, but there was also no increase until I opened the GUI again. This test was to see if there was some "background" leak from NEI, or if it would resolve itself by not opening the GUI (riveting gameplay for a modpack all out about being in a crafting GUI). The overall Spark Tree was similar to the one linked.
Java Version 25.0.1 OpenJDK
Note: Experienced this leak on 21.0.7 OpenJDK & 21.0.9 OpenJDK as well
Extra JVM Flags: -XX:+UseCompactObjectHeaders -XX:+UseZGC (When testing ZGC)
G1 Garbage Collector & ZGC both tested: ZGC seemed to handle it better/leak slower? (Unsure but seems to be the case)
Must clear "orphaned" memory after game is closed/gets oom-killed via:
sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'
P.S. I also noticed a similar type of leak with BetterQuesting and drawing items/blocks to the quest icons, there is a chance both issues are related, but I will still upload that Spark Profile to the BetterQuestion (GTNH) Issue Tracker BQ GTNH does not have an issues page, Where should I upload?
