Bug 475062

I cannot reproduce this. 

Can you share your .config/kwinrc

Sure thing. I'll both attach it and copy/paste the contents.

possible and set the bug status as REPORTED. Due to regular bug
tracker maintenance, if the bug is still in NEEDSINFO status with
no change in 30 days the bug will be closed as RESOLVED > WORKSFORME
due to lack of needed information.

For more information about our bug triaging procedures please read the
wiki located here:
https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging

If you have already provided the requested information, please
mark the bug as REPORTED so that the KDE team knows that the bug is
ready to be confirmed.

Thank you for helping us make KDE software even better for everyone!

Apologies. I didn't know I should manually update the bug status. It seems like something that would interfere with the person helping work on the bug, so the idea didn't even occur to me. It's updated now.

Removing "ElectricBorderMaximise=false" gives the EXPECTED RESULT.

I don't know what this setting is supposed to be for or how it is supposed to become set/reset.

Sorry for the delay.

I can confirm that removing "ElectricBorderMaximise=false" from my kwinrc, logging out, then logging back in resolved the issue. I'd never have caught that. Thank you kindly.

Life demands my attention, but when I get time, I'll try to see if perhaps a desktop effect or Kwin script added that line, and alert the appropriate developer. Hoping I'm doing this correctly here, but marking as resolved. I appreciate the help everyone.
