Mixer window channel large!!!

Hello, tell me why the mixer window channel sometimes becomes so great right where the indicators? the picture attached!

Now the window channel settings even became dark!

Hold alt while selecting the downwards arrow and select reset channel settings window (or something like that)

Damn, this is still happening? Wasn’t this reported as “fixed?”

Check write! Thank you!

press Alt as you said but nothing happens, apparently this is due to the heavy load of the project is buggy graphics!
