Screen goes 'dark' when running E-UAE in full-screen and Amiga resolution changes

Hi,

I'm running E-UAE 0.8.29-WIP4 on a Toshiba Tecra 8000 (P-II 400MHz... *groan*) on Slackware linux 11.0.

When running E-UAE in full-screen, if the Amiga changes resolutions the screen goes 'dark' (ie the light in the LCD goes very dim) and it does not come back regardless of change of resolution in E-UAE / X11 etc, until I log off (end XFCE session). When X-server is restarted for new login, the screen comes back up bright again.

Any ideas what is happening?
