Hi

I tried the official linux client of CEF137, the right-click menu is misplaced.

What linux distribution and version? Are you passing any command-line flags to cefsimple?

I'm also having this issue.. branch 7204 (M138) , happens on Ubuntu 20 with cefclient (also when using --use-alloy-style). On ubuntu 22 it won't display at all. On Ubuntu 20 it seems to be off on X,Y coordinates.
I also have this problem on my app using CEF displaying a custom context menu, it is also off.
In the attached image I'm doing a right click on the top left corner and it renders in the middle

I believe ubuntu uses wayland by default. Can you try with “--ozone-platform=wayland” and “--ozone-platform=x11”?

[waynelu]

I used ubuntu 2204 with X11 by default.
If start cefsimple with --ozone-platform=wayland, right click menu looks good and position is correct.
While with “--ozone-platform=x11”, the issue is observed. Same as no argument case.

How did you verify that this change is causing the issue?

[waynelu]

We found the issue is not observed in CEF release 137.0.4 but exists in 137.0.8
Then we compile and test the three commits in branch 7151 between the two versions.

I am the author of the patch. I confirm that it is the cause of the misplacement when running on X11. But the patch was necessary because menus were not working at all for Wayland. I am already taking a look on how to solve this
