Description:
After alt-tabbing out of and back into Empire Earth Gold Edition running fullscreen, a persistent ghost cursor image remains on screen for the rest of the session. The artifact does not disappear on refocus and requires a full game restart to clear. The issue reproduces on two separate machines with different GPU vendors (NVIDIA proprietary and Intel/Mesa), ruling out a driver-specific cause. Gamescope nested mode does not resolve the issue. Also tried playing the game through heroic, same issue, i followed this guide (https://ee.heavengames.com/cgi-bin/forums/display.cgi?action=st&fn=1&tn=38451) by the letter. nothing worked. Thanks in advance for the help.

Workarounds attempted:

• KWIN_DRM_NO_DIRECT_SCANOUT=1 — no effect
• DXVK_WINDOW_MODE=borderless — no effect
• PROTON_ENABLE_WAYLAND=1 — no effect
• GrabFullscreen=Y in Wine registry — was already set, no effect
• Gamescope -e -W -H nested mode — game focus broken
