I have three windows 10 PC's here with a variety of Lazarus installs of release versions, no trunks..

They all behave correctly.

 So maybe it's the fact that the trunk is being used could be a factor.

I see the same issue on Win 10 (v2004)/64 bit when I do this

- Start Lazarus trunk
- Click the "minimize" button in the title bar --> the app does not disappear in the task bar but remains as a minimized window in the work as - exactly as Alexey shows in his screen shot
- When I click the Lazarus icon in the task bar, Lazarus comes up again, but has an extraordinaily high main window. The component palette is about 430 pixels high while it has a height of about 50 pixels normally
- When I drag the bottom edge of that super-high main window the height suddenly jumps back its normal value.

Since this issue occured only recently it was easy to find the guilty revision: it is r63842 ("LCL: Improve TForm's bounds events. Issue 0036127, patch from Joeny Ang.", committed by Juha).

Juha, I hope you don't mind that I assign this report to you.

Ok, I reverted r63842 in r63882. Please test.
Reopening the related issue.

This seems to work also after r63888 (issue 0036127). Resolving.
