Game receives mouse input even when not the active window.

Issue:
If EverQuest is open in game and the user clicks and drags the mouse in another window that has focus (or uses the scroll wheel), those actions are also duplicated in EverQuest.

Version:
Since the 2024-06-19 patch, which included always-on-top related changes with how the game window interacts with the taskbar.

Steps to reproduce:
1. Log all the way into the game world.
2. Click on another window.
3. Right click and move the mouse in the newly active window.

This causes the mouse look to activate in the game. Left click and drag, right + left click, and scroll events are also duplicated back to EQ.

Configuration:
OS: Fedora 40 Linux
Wine: Proton 9.0-2

I am experiencing this in Linux, but others have mentioned similar always-on-top issues in Windows as well. Hopefully they can add more to this thread.

Notes:
I used a window inspector tool to confirm that the WS_EX_TOPMOST window attribute is set on the Game window. After removing the attribute, the game quickly restores the attribute the next time it is in focus. This happens even with the AlwaysOnTop set to 0 in the eqclient.ini. This happens in both the checked and unchecked state of the in-game taskbar overlap options.

I wonder if it is related to this seizure inducing behavior when mouse looking in EQ, my taskbar flickers like crazy when I mouse look.

Most annoying bit of this that I've run into is the scroll wheel. If I mouse over and scroll down a page in a browser it's common to have my view in EQ scroll out into 3rd person. To avoid it you can put focus on a chat window or something first but it is still annoying.

I had the same issue when using a custom wine version. Running standard wine 8.10 or 9.11 both worked for me. Might as well (or instead) try changing the backbuffer setting using winetricks. (orm=backbuffer vs orm=fbo)
