World of Warcraft Alt + Tab Causes Mouse Sync Issue

While playing World of Warcraft through Lutris, I’ve run into an issue where if I alt-tab into another window (like Chrome / Firefox to look something up) my mouse does something weird when I’m back in game where when I click icons / buttons, I have to position the cursor about half way down the button (sometimes underneath the button / icon altogether) in order for it to click / highlight.

This only happens if I alt-tab after launching a fresh sessions, but it’s consistent, especially when running a single monitor, ie: off of my laptop for instance, but doesn’t seem to be much of an issue when I have 2 screens up due to how borderless window works.

As a side note, there is no error or anything funky that pops up. It just happens once I alt-tab back in. It can only be remedied by closing out the game / lutris, and then starting up fresh again, but once I alt-tab, it comes back.

Any suggestions would be greatly appreciated.

what distro and windows manager are you using? Pretty certain this is a WM issue

Same here, alt + tab to look something up, alt + tab to switch back to wow, mouse position is almost half way down the button. But that’s not the only problem, this issue happens more than 90% of the time when starting wow for the first time after battle net client has been started.

Only fix is to restart wow and hope for the best.

Using ubuntu 24.04, default window manager.

Any help would greatly appreciated.

Distro I am using is Ubuntu 24.04 and using Lutris specifically to install Battle.net launcher and run the game. Nothing else is installed / tweaked to get it running.

I wonder if it is the wine version? I tested on Ubuntu 24.04 Cinnamon and Kubuntu 24.04 using the above wine version (installed from protonup-qt using add version and wine tkg) and could not reproduce.

I have been recommending this or if you have UMU enabled with lutris (git clone or Arch AUR) to use Proton Experimental for TWW

Getting the same issue here. Played with a bunch of different settings and wine versions and keeps happening on latest fedora. Anyone else?

I might have found a solution. I can not explain it why it even solves anything but maybe you can reproduce and mitigate the issue as well.

In the screen settings, my display was set to “Primary”. Instead I was explicitly setting my first screen as primary (Generic Non-PnP Monitor [1] instead of Primär in the screenshot blow)

That helped. It’s such a quality of life fix.
If somebody could elaborate why this helped it would be great. Anyhow, fingers crossed if that helps anybody.

environment:
Manjaro Linux
Lutris 0.5.18
fix tested with UMU, Proton Experimental, Proton GE 9-25

EDIT

my proposed way apparently is not a real permanent solution as at least for me the issue reoccurs after a new start of the game but once you apply the above mitigation fix with setting the screen, the cursor will properly set infinitely: no restart of the process needed to readjust the window + it won’t occur again when you tab out until you close it
