Klayout cells window is not responding

[wongmatthew73]

Regarding Klayout "Cells" window, it doesn't respond when I click on it. In the screenshot, when I try and click on the spm arrow to expand the list, it doesn't respond. If I double click anywhere in the "Cells" window, the window will move behind the main program window. I then hover over the area where the "Cells" window disappeared for it to reappear/move to the front. It's as though the window is a read only graphic. Everything else in Klayout seems to work properly except this. Is the Cells window locked?

Klayout 28.2-1 Ubuntu 22.04

I've tried opening multiple different projects and this scenario happens on all of them.

Can you try updating klayout? 0.28.2 is from December 2022, so more than a year old. There's a good chance that might already fix it for you.

If it doesn't, it might be due to having a really busy gds/oas. It might help to increase the number of rendering threads or wait until everything's loaded (for me that can happen on rather big / polygon rich designs, esp with fill and I have to wait a few seconds even after the UI becomes responsive again. Though disclaimer I mostly work with photonics not electronics)

@wongmatthew73 Any updates on this? Did you try with the latest version?

I am using Ubuntu 22.04 myself and can't see that issue.

You can try renaming your ~/.klayout folder to something else. This will clear the configuration that KLayout stores to persist window dimensions and dock status. Maybe this helps.

I'm also having the same issue on an Ubuntu 22.04.04 WSL2 instance running klayout 0.28.2. I'll try the update or clearing the configuration file. Update: the fix of renaming the ~/.klayout folder to something else worked. I did mv ~/.klayout ~/.klayout-tmp and restarted klayout and the window was responsive.
