Fullscreen games stutter and lag significantly under MangoWM. The same games run perfectly smooth under Sway and Labwc on the exact same system and wlroots version.
Environment:
OS: Void Linux (glibc, x86_64)
MangoWM version: 0.12.9
wlroots version: 0.19.3
GPU: Intel Xe-LPG (Meteor Lake, Core Ultra 7 155H)
Driver: xe (kernel DRM driver)
Reproduction:
Launch MangoWM
Run any fullscreen game via Steam (tested: Hades)
Observe consistent stuttering and frame drops
What I tried:
vrr:1 in monitorrule — no improvement
syncobj_enable=1 — made it worse
allow_tearing=2 — no improvement
Rebuilt MangoWM from source with xwayland enabled — slight improvement, stutter remains
Verified XWayland is running correctly
Launched via dbus-run-session — no difference
