Error messages when launching MacVim from a terminal window under Big Sur

[greglutz]

Whenever I launch MacVim from a terminal window under (recently installed) MacOS Big Sur, I get the following message printed in the terminal:

2020-11-16 12:13:39.585 MacVim[46460:1266156] Warning: Expected min height of view: (<NSPopoverTouchBarItemButton: 0x7f83b527cbb0>) to be less than or equal to 30 but got a height of 32.000000. This error will be logged once per view in violation.

I actually get four instances of the message, one right after the other.

This is "Custom Version 8.2.1719 (166)". The terminal I'm using is iTerm2 Build 3.2.9, running zsh. The launch of MacVim is accomplished by typing an alias that translates to "/Applications/MacVim.app/Contents/bin/mvim".

Same here, sometimes i get NSPopoverTouchBarItemButton message, sometimes i get this:

2020-11-17 06:06:25.577 MacVim[5841:177765] Warning: Expected min height of view: (<MMTouchBarButton: 0x7fa9714b1a60>) to be less than or equal to 30 but got a height of 32.000000. This error will be logged once per view in violation.

Confirmed on Big Sur. Custom Version 8.2.1719 (166) from HomeBrew. Happens regardless of the Terminal

I also get the error, upon start-up of MacVim, and when I switch INTO insert mode.

[balena]

Same here. It happens once at start and again every time I switch to insert mode.

I am also getting the warning.

Here is my mvim --version if it helps

Duplicates #1114

[ychin]

Thanks for the report. Let's use #1114 to track this. Closing this for now. The next release should have this fixed.

I have still had the same problem as you mentioned above on PyCharm.

Has this issue been solved? experiencing the same with macOS Monterey version 12.3.1
