Hello @aiddya. Thanks for reporting this and helping to make Electron better!

Would it be possible for you to make a standalone testcase with only the code necessary to reproduce the issue? For example, Electron Fiddle is a great tool for making small test cases and makes it easy to publish your test case to a gist that Electron maintainers can use.

Stand-alone test cases make fixing issues go more smoothly: it ensure everyone's looking at the same issue, it removes all unnecessary variables from the equation, and it can also provide the basis for automated regression tests.

Now adding the blocked/need-repro Needs a test case to reproduce the bug label for this reason. After you make a test case, please link to it in a followup comment. This issue will be closed in 10 days if the above is not addressed.

Unfortunately, without a way to reproduce this issue, we're unable to continue investigation. This issue has been closed and will not be monitored further. If you're able to provide a minimal test case that reproduces this issue on a supported version of Electron please open a new issue and include instructions for reproducing the issue.

Why is this closed? This bug still exist. For example VSCode is affected by it. Starting VSCode with --ozone-platform=x11 does show a window shadow - lunching with --ozone-platform=wayland does not.
Providing that window.titleBarStyle is set to custom.
