I'm on Debian 12 Bookworm, KDE 5, Wayland.
Installed current OXCE from this link
https://openxcom.org/oxce/release/Extended-7.14-ddeea35e9-2024-08-31-bionic-x86_64.7zAlso I'm in XCom Files mod.
I'm using an external USB keyboard + mouse connected to my laptop.
I have the impression that in Ctrl+Mouse click combos, the there is a tiny delay in the activation of the ctrl key.
For example, when I want a soldier to drop a weapon in the equipment screen, I have to do it as Ctrl...tiny delay...left click. Without the tiny delay, the weapon will be selected like from an ordinary left click.
Another example: Ctrl...tiny delay...right click on a weapon will set a red square in the upper right corner of the weapon. Without the tiny delay, I get the yellow square as from a ordinary right click.
In constrast to that, Ctrl+key combos like Ctrl+E for getting the "no experience yet" window works without any delay. Also, using the primary laptop keyboard, the problem disappears [edit: not so sure any more about the latter...].
I'm not sure if this is an OXCE problem or if it comes somewhere from the OS.
Posting it anyway as it is a bit annoying. Maybe someone has an idea / is experiencing the same problem.
