Yes, I tried had to make LO to crash KDE (plasma), but KDE's compositor wouldn't have any of it. No matter how much or how fast I moved the mouse over the menu to cause tooltips to overlap as they popped up and disappeared/reappeared, KDE continued to display them without freezing up. If I moved too fast over the tooltip generating area they just blurred a bit without rendering fully their content in the milliseconds they were given to render, before the mouse moved on to the next area. Such blurring would cause a freeze on evas/e. Conclusion: Plasma compositor will not cause the same crash by libdri. > > https://pastebin.com/Y6SxaKGF > > now to this... it doesn't tell me more than it did before... it's a fence > sync within the driver layer. it's a problem between the driver and itself > across process boundaries. if you want i can explain what fences are and > their purpose (in general) and why this would be the case and i can > probably narrow down where the issues are being caused in the x 2d + dri > driver stack... but it'll be a long explanation. i do not know the DETAILS > of the fence implementations down at the dri level... but i do know what > fences are, what they in general do and why this tells me the issue is not > something we can solve in efl... > > if you want the details - let me know. otherwise know that this is a bug you > likely have to file with the dri3/mesa/xorg 2d/radeon driver people... :/ I thought this was a radeon driver problem. On some further testing shows this *also* occurs on Intel! An old Acer Incorporated [ALI] Mobile 4 Series Chipset (ICH9) Integrated Graphics Controller crashed in the same manner. This is using the i965 & intel flags in mesa, rather than r600/radeon/radeonsi. So it does not seem to be radeon specific. I've tried with mesa-17.0.6 which is when the problems seem to have started and with mesa-17.1.3. I've started with a report to Gentoo for now and will see what they advise. -- Regards, Mick ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
