Windows build number: Microsoft Windows [Version 10.0.18362.657]
PowerToys version: v0.15.1
PowerToy module for which you are reporting the bug (if applicable): FancyZones
I just had zones set up before the update to 0.15.1, which split my entire 4k desktop into subsections.
After the update, the zones do not take my whole screen size anymore. It is as if they shrunk in size, and I cannot stretch them back, so a section to the bottom and right of the screen is lost.
We can see in this picture that the size of the zones doesn't match the actual size of the screen. But it did before the update.

Here is my zone-settings.json file. It seems the percentages don't add up to 10000. I do not know if they were like this before the update:

Also, I do not know which version I had previously... can I see it somewhere? (I think it was not 0.14).
Hi @Yoann-Pearson
thank you for reporting the issue.
We'll investigate the settings you posted to check what's wrong with it.
In the meanwhile, you can recreate the layout starting from two rows template and it should work (I just tested and it worked, I can send you the settings if you wish).
Yes I recreated my zones already and it is true it works now. But I just wanted to inform you guys that something went wrong in the upgrade / new version process somewhere.
@Yoann-Pearson
we reproduced the problem and working on a fix.
I had the same problem. Right after installation, everything worked perfectly, but this was no longer the case after a restart.
The fix is now available in 0.16 https://github.com/microsoft/PowerToys/releases
