sub menus of the context menu do not fit the screen anymore. I'm not sure which version introduces this behavior, the Windows explorer shows the context menu correctly. Since Tortoise Git has a very long menu, it is easy to reproduce this behavior. But also the "send to" menu can be used to show this behavior.
I'm using a 4k screen with a zoom level of 175% + a FullHD screen. The issue is still there if I have just the 4k screen enabled. If you need more details, I'm happy to provide them.
Is it just that the bottom of the last item is slightly off-screen, or are there whole items missing?
If it's just the former, we noticed the same a few days ago and have a fix in the pipe for the next beta.
Mixed DPIs still trigger a number of bugs in Windows, so that could be a factor. If more than just the bottom of the last item is being cut-off, could you see if it still happens with just one screen enabled, after rebooting?
(Rebooting is needed to fully update DPI changes, while having just a single monitor active will check what happens without mixed DPIs.)
