Are you sure that you are running the latest executable? No corruptions here, neither with the default skin, nor with Neutron.
Are you running Win 8?
I double checked the exact version by looking at the bottom of the Options and stuff page. It says 126.96.36.199.
Just because I have too much time on my hands:
188.8.131.52 - seems OK on all skins except Rated alpha where the background of the skin is a big black square with a small white square in the upper right corner and a white bar on the lower right corner.
184.108.40.206 - don't have it.
220.127.116.11 - same as 18.104.22.168.
22.214.171.124 - Rated alpha does not show on the desktop at all, even when running. Can only control by right clicking the system tray icon and picking Options and stuff and manually changing the skin to something else. Other skins show no ill effects.
126.96.36.199 - don't have it.
188.8.131.52 - same as 184.108.40.206.
220.127.116.11 - As originally described. Rated alpha crashes XMPlay when auto changing from mini to regular mode with mouseover. All other skins have the mini-mode corrupted (but no crashes). Many other skins have bright green bits in the corners or elsewhere which are probably remnants of transparent color that didn't matter when they were used with previous versions.
Skins that I have on hand:
MMD3 (three different colors)
WAModern (three different colors)
Edit: I also have a laptop running Windows 8. I'll give it a try later this evening.
