Browser getting white after navigation and some SPA actions

[ndesktop]

I have seen this as well, mainly WM_PAINT related (but I am using a completely unrelated UI so I don't know how relevant this is), although my /STACKSIZE is even higher than 0x80000.

Checked the difference of the command lines:

cefclient.exe

Code: Select all

"C:\dev\other\CEF\7499\target\chromium\src\out\Release_GN_x86\cefclient.exe" --type=renderer --enable-dinosaur-easter-egg-alt-images --origin-trial-disabled-features=CanvasTextNg|WebAssemblyCustomDescriptors --no-pre-read-main-dll --user-data-dir="C:\Users\Johann.Scheiterbauer\AppData\Local\CEF\User Data" --video-capture-use-gpu-memory-buffer --lang=en-US --device-scale-factor=1 --num-raster-threads=4 --enable-main-frame-before-activation --renderer-client-id=10 --time-ticks-at-unix-epoch=-1777445426074323 --launch-time-ticks=716873771605 --metrics-shmem-handle=5100,i,18382299523681791953,12699670339846898511,2097152 --field-trial-handle=1832,i,12514319520834200309,14429425564990040452,262144 --disable-features=GlicActorUi,LensOverlay --variations-seed-version --trace-process-track-uuid=1188252717 --enable-logging=handle --log-file=5080 --mojo-platform-channel-handle=5068 /prefetch:1


jcef

Code: Select all

The differences are:

cefclient.exe

Code: Select all

--disable-features=GlicActorUi,LensOverlay


jcef

Code: Select all

--libcef-path="C:\builds\HEAD_CI\bin\win_x32\libcef.dll" --no-sandbox --disable-features=EnableHangWatcher,GlicActorUi,LensOverlay


First thing catching my eye is the no-sandbox mode of JCEF which is different to CEF/Chromium/Chrome.
Some time ago we had problems with SVG drawn radio buttons in that mode.
Also will check the additionally disabled feature for jcef (EnableHangWatcher).

After some testing and fooling around with parameters the following change did the trick:

We took the jcef.sln and changed the linker option for the STACK size from "0x80000" to "0xC0000" which is then 12 instead of 8 MB.
That worked.

Has anybody experience about good values for this configuration?

ndesktop: You mentioned something, which value do you use?

/STACK:0x00120000

OK, so you increased it from 512 kB to a bit more than 1 MB, correct?
Did you observe any side effects?

Correct.

Not really. As I said, I have sporadic stack overflows but they are not specific to 32-bit, and usually the cause is the UI layer (sciter) and not something CEF or Chromium-related.

[Phylanx]

We are now using an increased stack size of /STACK:0x100000.
Tests look promising, we hope the best

Thx for your support!
