Solution

idk

Additional context

The bug appears in the 1.2.7. Also you have to restore this backup first and then start to scroll boorusphere_backup_2023-02-12-10-41-29.zip In any case, also without the backup i can notice that the 1.2.7 is not as smooth as the previous versions since there is a little bit of lag while scrolling(1.2.7 and next). If you add the backup the lag is just enchanted. Before the 1.2.7 i never encountered this kind of lag.

Maybe because i added a lot of tags in the blacklist but in the previous versions never saw that kind of lag (despite having a lot of tags blacklisted), always smooth. I noticed that in the 1.2.7 the backup feature was implemented.

have you tried disabling blur ? blur is quite an expensive operation on android (especially on low to mid-end devices)

Palloxin commented 1 year ago

I never enabled that option. Also the blur by default is disabled so when i tested it on other versions i am sure it was disabled too

I tried on emulator with 1.5gb ram and 4 core, no lags while scrolling. It's also on debug-mode, which is WAY slower performance compared to release-mode.

my device has 3gb, idk how to emulate it. did you restore from the backup i uploaded? With a clean installation(no backup restored, no tags blocked) the lag is very little but still noticeable compared to previous versions of 1.2.7

I think the problem is device nor Optimize. As I can see it's trying to load a bunch of pictures at the same time that may why it's lagging.

Because I have slow internet, I haven't experienced the lag.

well if it was a device specific issues then nothing we can do except waiting for another flutter update; at least until new rendering engine (Impeller) is stable enough.

Is there a way to send you some kind of log, debug mode or something else that could help you understand how my device operates your app?

Closing as the issues are not reproducible even on low-spec emulator configuration
