Just Hear yesterday about this beta release, and it's amazing bunch of fixed issues:
- the screen tearing is fixed... such amazing, test on one Intel and two Nvidia Video system from live CD (Nuveau / No proprietary Nvidia drivers as is a live CD Image) the issue is completely fixed. Probably I should thank for this fix to @vkareh as I see is doing a lot of good work all over the Mate Desktop, not just only to Marco Compositor.
- Mate panel configuration this time looks it change nicely.. no more crash or inconsistency, even on first live run from all three systems only one start with consistent panels, the other two, one start with a missing panel and the other with both panels on top... but after change from mate tweak it gets consistent ... so hope only a issue somehow related to live image.
- Inconsistent size of Icons in Control Center remain as issues for quite a long time, not evaluating the icon size consistency on desktop, probably related and also not fixed.
So as a conclusion solving the tearing on desktop, is the most important one fix in this release.
Mate Desktop is the best Desktop Linux has, and with this release is coming close to high quality and perfection ... hoped also 32bit systems have benefited from this ... but that's it. And also hope my third top issues (with inconsistent control center /desktop icon size) will be addressed some day (as I do not understand how in 16.04 RPI image icons are consistent)
Just wait for upgrade when released and available...
