In one moment my Mattermost chat changed from using the whole screen to use only a section, as shown in the photo, there is a white space on the right and on the bottom.
Could someone tell me how to set it that the screen chat is display in that white parts also?
There is an issue with Mattermost Desktop 3.4 where increasing or decreasing font doesn’t work properly.
This should be mostly fixed with the next release, so that after you click at least once somewhere in the app, it’ll work properly. A complete fix for it is still in the works.
In the meantime, if you reset to default text size, you’ll be able to see the chat window at full screen. To set the default text size, you can either:
Press CTRL + 0 on your keyboard
Go to View > Actual Size in the menu bar at the top of the Windows app
