Given your answer, i decided to just go ahead & manually list below the Plasma/KWin settings i routinely use [ever since Mint 17 KDE4] - these have become a standard, important, part of my workflow, & i'm not prepared to dump them [ie, if a distro can't
reliably support them, then i need to find another distro].
Compositor = OpenGL2.0 or 3.1 [if the distro is crash-susceptible, neither of these is better].
Desktop Effects = Zoom, Fade, Fall Apart, Glide, Login, Maximise, Morphing Popups, Scale In, Screen Edge, Sheet, Sliding Popups, Thumbnail Aside, Wobbly Windows, Logout, Magic Lamp, Dialogue Box Parent, Slide Back, Desktop Cube Animation, Desktop Cube, Desktop Grid, Flip Switch, Present Windows.
Screen Edges = Top LH Corner is
Desktop Grid; LHS is
Present Windows, Current Desktop; Bottom LH Corner is
Activity Manager; Bottom is
Desktop Grid [yes, that's deliberately a duplication, as the other one often stops working (in Maui;
never in oS TW)]; Bottom RH Corner is
MinimiseAll/ShowDesktop; RHS is
Present Windows, All Desktops; Top RH Corner is
Desktop Cube - Cube.
Window Management = DEactivate both "
Maximise windows by dragging..." & "
Tile windows by dragging...".
Other Settings =
Switch desktop on edge: Only when moving Windows.
Virtual Desktops = 9, with 3 rows [ie, giving a 3x3 grid].
Activities = n/a... the same KWin crashes happen in my Test Scenario [on the susceptible distros] regardless of me setting these as 1, 2 or 3.
Please note this new info:
This morning, following on from your suggestion yesterday for me to try booting from Maui LiveUSB [which sadly proved that the "real" Maui
KWin crashes under my
specific test scenario* ALSO happened here, Live], i remembered i have some older other Plasma5 ISOs
from last year or earlier this year (ie, NOT recent Plasma versions], so i burned them to USB & booted from them in Tower this morning. The results were interesting:
*
Test Scenario: Configure KWin as above, then open various pgm/doc windows on multiple VDs, then display
Desktop Grid then drag&drop individual windows from VD to VD keeping
Desktop Grid displayed [the crash does not usually occur if DG is closed the instant the drop is done].
NB: Must test in "real" installations, or LiveMedia, NOT VMs [these crashes
never happen in VMs].
1.
KaOS [P5.8.5] - rock-solid!! Not a single
KWin crash despite my rigorous test. It felt as robust as openSUSE TW does on Lappy.
2.
KDE Neon [P5.7.5] - this crashed
KWin as badly as Maui does, when doing my test. Frankly i was shocked at this, but then i wondered if this might make sense, given Maui uses KDE Neon for Plasma5...?
3.
Mint 18 [P5.6.5] - identical
KWin crashes. I can't say i was surprised, as instability was THE reason i abandoned Mint KDE last year & found Maui.
Surprisingly openSUSE no longer provide their own LiveMedia of their ISOs, but i found this
https://userbase.kde.org/Live_CDs_-_a_wa...o#openSUSE +
http://download.opensuse.org/repositorie...mages/iso/ & am downloading a Live ISO whilst writing this; i plan to soon boot from this & evaluate how it performs with my "
KWin Test" on Tower.
