More on spelling errors not being marked as you type in large ODT documents, vs. smaller ones

Mainly due to stiff arthritic typo-fingers, plus age, I much depend on the marking (red squiggly line) of spelling errors, however, I have found that in large ODT documents then such are not being marked until I right click, if then, versus simply continuing to type. See image.

PC specs: 128GB RAM; Ryzen 3200GB CPU; NVME and SSD drives; Windows 11 Pro (I thank God for all).

Please do not suggest the default solution of “Reset your user profile” which is not going to be considered a solution. This issue is not new, and since spelling errors are marked if I right click in a large document then the dictionary is set. Paragraph styles are the same.

Please attach a sample file, without private information, and paste the information in Menu/Help/About LibreOffice, there is a copy icon.

Since the issue is only with very large files, then that is what I should send, but attached is a copy of the default file I am using. As for /Help/About LibreOffice, there is no copy icon, but also attached is an image.

Hope this helps. Thanks

What do you suppose the icon to the right of Version Information might be?

Sorry. I did not readily recognize that icon as a link though I should have.
Version: 24.2.0.3 (X86_64) / LibreOffice Community
Build ID: da48488a73ddd66ea24cf16bbc4f7b9c08e9bea1
CPU threads: 4; OS: Windows 10.0 Build 22631; UI render: Skia/Vulkan; VCL: win

The build link opens in a web page: https://git.libreoffice.org/core/+log/da48488a73ddd66ea24cf16bbc4f7b9c08e9bea1

It might be a graphics issue. Try the following setting and see if it resolves the problem.

Click Tools - Options - LibreOffice - View , tick the box Force Skia software rendering and allow LibreOffice to restart.

Did so. Loading all previous documents now. Typing in the same large ODT doc as before shows that typos are now being marked as errors as I type them, so perhaps that fixed it, or the issue is with Windows itself, or perhaps Ryzen integrated graphics.

Need to get some sleep now. Thanks for your help. May God bless.
