Shift does not work properly with some Plasma keyboard settings

[FelicitusNeko]

Describe the bug

Several elements in Anti-Idle: The Game require to shift-click to perform certain interactions (sell items in Battle Arena, remove trees in garden, confirmation for destructive actions). However, it seems not to detect Shift pressed state.

Steps to reproduce (one example):

• Start a game
• Play long enough to get to the Garden
• Plant a Free tree in the Garden
• Shift-click on the Free tree to remove it
• An error message is displayed that there is already a tree in that plot, and to shift-click to remove it

Expected behavior

In this case, the tree would be removed from the Garden.

Hi @FelicitusNeko! I've tried to reproduce this bug, but on the latest nightly (2024-08-19) it seems that everything works, see the recording below. Are you sure you used the desktop app?

BTW On the web version it works too for me

[FelicitusNeko]

Yes, I'm using the desktop app. I've tried multiple times to shift-click on things, and it doesn't work for me. Ctrl-click works fine. Some elements such as Battle Arena skill +/- buttons and LolMarket buy/sell have you hold Space and click, and that also works. Only shift-click doesn't.

Could you run the following SWF and check whether it says Shift when shift is pressed? pressed_keys.zip

Also please verify whether you can input uppercase characters while pressing shift in the following SWF: basic_input.zip

[FelicitusNeko]

The basic input one does allow to enter capital letters. Also worth noting that any input in Anti-Idle that requires pressing Shift and a key seems to work.

The pressed keys one shows KeyCode 20 when I press Shift. It does not go away when I release Shift. Pressing Ctrl and Alt show Ctrl and Alt, and those do go away when I release them. Any other key seems to work fine.

[kjarosh]

So that gives an important insight to the problem: code 20 means CapsLock. Do you perhaps have Shift remapped to CapsLock? Or any other idea why that might be the case?

[FelicitusNeko]

I had enabled this option in Plasma keyboard settings. Turning it off makes the pressed keys tester properly recognise Shift. Trying it in Anti-Idle, it's now correctly allowing me to sell items or remove trees. It's weird that it would recognise one Shift key as Caps Lock, as the rest of the system seems to properly handle it as Shift being held just fine.

Other options in this list that modify the relationship between Shift and Caps Lock also affect how Shift is processed in Ruffle. Only with them all turned off does Shift get processed correctly.
