I have a issue for Firefox depiction. Procedure for reproducing is as follows: 1) Set Mozilla's dark theme. 2) Minimize the Firefox window. 3) Restore the Firefox window, white border line draw the window. <Maximize the Firefox window, next restore the window size, white border line is disappeared.> I tried trouble shooting mode, refresh the Firefox, reinstall the Firefox, but issue does not solve. Is there any way to solve this issue without maximize the window?
