We have to invalidate the current mode cache if there are pending RRNotify events. The performance hit on EnumDisplaySettingsExW is around 7%.
Also call X11DRV_DisplayDevices_RegisterEventHandlers in x11drv_init. Otherwise, RRNotify events will only be handled in the explorer process. --- dlls/user32/tests/monitor.c | 10 +++++----- dlls/winex11.drv/event.c | 2 +- dlls/winex11.drv/window.c | 1 - dlls/winex11.drv/x11drv.h | 1 + dlls/winex11.drv/x11drv_main.c | 1 + dlls/winex11.drv/xrandr.c | 28 ++++++++++++++++++++++++++++ 6 files changed, 36 insertions(+), 7 deletions(-)
