The mobile and TV clients are often limited to the codecs with hardware acceleration. Or just selecting a lower bitrate on the client will cause transcoding.

Filesystem permissions

For many apps it is not an issue and provides additional security but in other cases it’s very annoying and not trivial to fix.

Example1: opening a .docx from Thunderbird flatpak with OnlyOffice flatpak does not work out of the box.

Example2: mpv and VLC flatpaks work well for local files, but fail to open network shares from Dolphin.

I think a possible solution would be runtime permission dialogs when denied access.

It is not necessary but still better to run both online discard and batched fstrim. from man:

Also, a device may ignore the TRIM command if the range is too small, so running a batch discard has a greater probability of actually discarding the blocks.

I’m not 100% sure, but for me it caused a similar “freezing” or unresponsive experience when the daily cleanups run in the morning. If there was a freeze after every (even short) sleep and resume that might be a different issue.

Yeah it’s disappointing that such an annoying bug is still present and quotas are enabled without warnings. You could continue using Timeshift, the only feature quotas provide is the individual disk usage of the snapshots.

What did you use to manage snapshots? For e.g. timeshift enables quotas and that can cause freezes when deleting old snapshots.
