Description filip.klingelnberg 2019-08-08 17:15:39 UTC

Description:
Unusable presenting feature (F5) in Impress probably because of a scaling issue with bigger screens at least with 1440p displays (2560x1440 pixel) resulting in bad user experience.

Steps to Reproduce:
1.Create a presentation (one slide is enough)
2.Press F5 or in the menu Presentation to present the slides on your monitor
3.Now you should expect to see your presentation in full screen on your monitor

Actual Results:
You will see incorrect presented slides on your monitor (distorted). Often the lower part of the slide get shown above the upper part of the slide. Sometimes some parts are missing.

Expected Results:
Viewing the actual complete slide.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
Tried with new installations from various versions of impress also with stable ones without success. Only when you turn the resolution down to 1080p (Full HD) the slides get shown correctly.

Change to OpenGL rendering, or CPU only rendering -- so as to disable Hardware Acceleration.

Change in the Tools -> Options -> View panel, and restart.
