I am unable to have small text on the right side of the screen when in landscape mode. It is cut off past 240 pixels.
Everything works in portrait mode, or in landscape mode when the text size is 2 or greater. All the sample sketches work flawlessly, so it's not a wiring problem. Pictures attached.
2.8 tft touchscreen. No text on right side of display.

Could you post your code and a description or drawing of your connections between it all?
Please use the code button as shown below.

Re: 2.8 tft touchscreen. No text on right side of display.
Here's the code. I started with the paint example and edited it from there.
All the wire connections are as per the example.
Here's the total code:
By setting tft.setTextSize(1); to tft.setTextSize(2);, then it prints to the right margin and wraps around correctly. But I want to be able to print to the right margin in font size 1.
Here's a picture of the wiring. I suspect it isn't the problem because the display works perfectly otherwise.

Re: 2.8 tft touchscreen. No text on right side of display.
Just playing around with it some more tonight. I cannot draw a line past 240 pixels. It is just cut off on the x axis but draws on the y axis (ie drawing a sloped line becomes vertical at x=240, if that makes sense - sorry no picture. my phone is dead).
I can draw rectangles without a problem past x=240. I wonder if there is a bug in the library that prevents text or lines past 240. Have you been able to duplicate the problem?

Re: 2.8 tft touchscreen. No text on right side of display.
Here's a couple more pictures. The rectangle function works OK. The filled circle function works OK. The line and hollow circle does not draw past 240 on the x axis.
First the code that is used:
In this next picture, the only difference is the font size is set to 2 instead of 1:

Re: 2.8 tft touchscreen. No text on right side of display.
I'm experiencing the same issue. Lines and text get cut off when in landscape (3) mode. I tried different rotation modes, enabled/disabled text wrapping, and changed font size. The problem does not occur with a font size of 2, as mentioned by the OP. This issue has been around for several months; I hope it gets fixed. Thanks!

Re: 2.8 tft touchscreen. No text on right side of display.
Oooh thats in 8-bit mode. Yeah 8-bit mode is the TFTLCD lib not ILI9341 lib - for now, you can try using SPI mode (fewer pins, slightly slower, doesn't have this bug!)
We didn't catch it before because we kept testing it in SPI mode!
We'll put in a github issue to look at this shortly!

Re: 2.8 tft touchscreen. No text on right side of display.
Too late: my project is already set on using 8-bit mode! Luckily the font size I am using is 2 so I don't have a pressing need for a fix. But I do plan on using this screen in future projects and the fast redraw of 8-bit mode may be preferred once again. Thanks for looking into it!

Re: 2.8 tft touchscreen. No text on right side of display.
Thanks for providing the great sketches to reproduce the issue. I dug into it a bit more and found there was a bug with the rotation hard coding some limits based on the portrait orientation. I just updated the library to grab the correct limits based on rotation and it looks like it fixes the issues with your examples. Grab the latest library code and give it a shot, let me know if you still see issues.
Here's a quick look at the working example if you're curious:
