Describe the bug

Touch doesn't work properly in the latest version of Calendar (v6.23.1) on Google Pixel 8 Pro running GrapheneOS. For example, in "Monthly and Daily view" the touch recordings are recorded diagonally, e.g. - press on 8th, it will record 7, then press on 15th, it will record 13th, then press on 22, it will record 19th, press 29th. it will record 25th. so going down diagonally from 7 to 25th, etc.

It is not a phone issue as all other apps are working as expected, only this app glitches. Other users also reported the exact same issue on Simple MobileTools Issue tracker. We believe it might be related with Pixel 8 Pro's screen resolution (1344x2992).

To Reproduce
Steps to reproduce the behavior:

1. Open the the calendar in any view, for example, Monthly View.
2. Tap to 5th - it will select 4th. Then tap to 16th - it will select 14th, etc. So it doesn't record the taps properly.
3. If we press and hold the entry (for example, 5th), it will actually highlight the 5th, so it detects we press the 5th, but if we tap 5th, it will still open 4th instead.

This is happening with the out-of-the-box settings.

Expected behavior

Tap should work properly in any view, that is - if we tap to 5th, it should open/select 5th, etc.

Yep same. Needs fixing for sure.

Folks, do you have any estimates on this by a chance? Thanks.

Can report that I also have this bug with the exact same environment.

Forced to move to Etar, which is unfortunate.
Even manual entry with specific dates places it in a completely random other date. Completely unusable on Pixel 8/pro

I found the bug and opened a PR #154 , the problem was that the screen width is exactly divisible by 7 (days per week / columns) and it checked if the element fits onto the screen by doing a "less than" comparison instead of a "less or equals" so it wrapped the last element into a new line.

Thanks a million for this!
