Other problem.
I've found a site making Dooble close each time!
process used: (using duckduckgo as default search engine)
entre wuwt into the link field + enter
duckduckgo opens and first found entry is whattsupwiththat.com
Clic on this first found entry and wuwt start to load....
Wait until end of load.... before the end, Dooble closes
Which version of Dooble are you using? In the upstream version 2025.02.08 Duckduckgo and Google were "removed".
OK, nothing recent. Here, I don't really get the low shared memory dropping, just high shared memory dropping, but I do have the DLL's marked high. I'm using Qt version 6.2.8 (runtime 6.2.11).
It still locks up too much for me to use it much. It's a shame dmik has moved on.
I meant Dooble releases. This one saw using a profile on Qt6 to fix the visited links colour. Qt5 always used a profile.
Also how is the French translation working for you? There was an update, attached.
I meant was the simplebrowser in single process mode to make a better comparision.Code: [Select]set QTWEBENGINE_CHROMIUM_FLAGS="--single-process" simplebrowser.exe
You might want to try even lower on the VIRTUALADDRESSLIMIT, perhaps 2560 for a bit.
The potential problem is if PCI address space on your machine is larger then expected.
Now, tried simplebrowser from QT6.2.11
(I set correct environment and run simplebrowser)
At open time + initial link page load, it took about 30M of shared low storage
I check QT ver and 6.2.11 is displaied
Opened, 2, 3, 4 tabs with link, no shared low memory decrease ! it works
Was this with single process?
Here I don't find Dooble-Qt6 keeps using up lower shared memory, it does eat up high shared memory. Also at one point I lowered my VIRTUALADDRESSLIMIT from 3072 to 2944 which cured a lot of the hangs here. Might want to try lowering it depending on what it is set at.
Same QT6 DLLs as I have set for QT5 are set highmem (no differences between QT5 or QT6)
QT5 = ok
QT6 = memory issue (may be this could explain many crashes or silent close all seems to have !)
I doubt this is the cause of the crashes/silent closes - qt6 webengine builds have been out for ~2 years now and nobody has commented on low memory being exhausted previously. Not saying you're not seeing the behaviour.
99% of the OS/2 specific code is the same between Qt5 and Qt6 - so I'm struggling to explain this, hence my suggestion to ensure the DLL's are marked high. Which Qt6WebEn.dll build are you using, and do you see the same behaviour with all releases?
