Lag and crashing with Flutter v3.41

[zer0boi]

Describe the bug
Ever since the last update, everytime i open aves everything gets more and more laggy until either aves or the whole phone crashes.

To Reproduce
viewing the gallery or deleting an item (doesn't happen when viewing the settings for example)

Expected behavior

Additional context
I tried removing the widget and it weirdly made it better butonly temporarily, clearing cache only fixed it temporarily.

Behavior is inconsistent, but scrolling or clicking or deleting items usually does the trick, sometimes just opening the app freeze things

Related issues:

• v1.14.0 not visible in Accrescent #1960
• Too heavy on memory #1480
• App runs slowly starting from 1.12.6 #1474

Possibly related Flutter issues:

• (Willing to PR) "RSS" memory becomes >1GB while other parts are small - is there any utilities to debug this? flutter/flutter#128099
• Debug ui.Image memory consumption problems easily - e.g. add a "debugDumpNonDisposedUiImages" flutter/flutter#128105

Possibly related Flutter flags:

• EnableAndroidHcppAndSurfaceControl: toggle Hybrid Composition & Surface Control (for Impeller), the latter being previously referred as "AHB swapchains" in App runs slowly starting from 1.12.6 #1474
• DisableMergedPlatformUIThread: toggle UI and platform thread merging, legacy flag ("This flag is disabled and only exists for the purpose of throwing an exception when used.")
• MergedPlatformUIThread (values): toggle UI and platform thread merging

Here's a build of Aves using some configuration flag that supposedly disable Flutter thread merging:

It is a release build of the libre flavour. If it collides/replaces your original build, I can build another flavour so that you can keep the one you already have without reset.

@zer0boi could you please try this build and let me know whether you experience the lags?
@kmcbest could you please try this build and let me know whether you experience the slow keyboard issue you had in #1474?
@1BazBiz could you please try this build and let me know whether you experience the large memory usage you had in #1480?

I've tested it, it's a clean install since it's libre flavor. After scanning my 80000+ images swiftly, the app hangs when it shows the thumbnails, then crashes. And it hangs and crashes every time after, I don't even have time to enable logs. This is on my main Redmi phone with MediaTek 9200+.
On the other hand, this build runs well on my old MI 8 with Snapdragon 845, although it only has less than 7000 images on it, most of them untagged.

I dunno if the number of images and number of tags are impact factors on the performance, I've asked Gemini to write me a script that generates a lot of simple color images with random tags. If you want to generate you can use it:

import os
import random
import uuid
from datetime import datetime
import xml.etree.ElementTree as ET
from PIL import Image, ExifTags
from concurrent.futures import ProcessPoolExecutor

I generated 10000 images each with 5 random tags, and put them on my old MI8 phone. I started Aves profile build and it catalogues the images at 50 pic/second speed, but never hangs nor crashes. After the cataloguing I've got 40000+ tags, so as I said in the other discussion, the app will freeze if I have the 'top tags' section expanded.

Anyway on MI8 the app runs and doesn't crash, which is not the case on my RedMi K60 . There must be some problem with certain Mediatek cpu when running Flutter.

-- Edit

After several crashes, the profile build agreed to run on my Redmi K60. After cataloguing, the 'slow keyboard' effect is still there unfortunately.

I still have high memory usage (and crash at the end) with this build. See screenshot.

Tested it, the lag & crashing is still the same
