Description Alexander 2023-06-20 08:45:27 UTC

In dolpnin 23.04.2-1.fc38 changing icons scale with mousewheel works incorrectly: both wheel directions makes icons bigger unitk maximum then smaller.

Dolphin 22.12.3-1.fc38 works fine: at mouse wheel up icons become bigger, at  at mouse wheel down — smaller.

Reproducible: Always

Steps to Reproduce:
1. Install dolpnin 23.04.2-1.fc38.
2. Open any folder.
3. Scroll mouse wheel up and down.
Actual Results:  
Both mouse wheel up and mouse wheel down makes icons bigger until maximum then smaller until minimum.

Expected Results:  
At mouse wheel up icons become bigger, at  at mouse wheel down — smaller.

Not sure if this is important, but I use Logitech Wireless Mouse M310 (cheap and simple model without any tricky behavior).

Update.
Bug viewable only right after starting dolphin.
After using scaling functionality you should restart dolphin to catch this bug again.
Holding ctril wheel up while scale lesser than ⅔ or ¾ from maximum, then not releasing ctrl wheel down.
In this case scale continue to gow then stuck at maximum, ignoring mouseweel rolls.
After releasing ctrl and some mousewheel rolls scaling behavior will reset from buggy to expected until restarting of dolphin.
