#1506 Editor font appearance when resolution is same but screen physical size is different

[Anonymous]

I use Texstudio on a 15.6' Thinkpad E540 laptop with 1920x1080 resolution, with a 27'' LG monitor also at 1920x1080. The laptop monitor is the primary display.

Everything on the primary display appears ok. When I move to the 27'' monitor the fonts on all lines (except the current line) appear 'enlarged' (see attached figures).

A possible workround is to change the display settings of the monitors. More specifically the "Change the size of text, apps and other items) to identical values. In my case the laptop screen is set by default to 125% and the LG monitor is set to 100%. When I change them both to 125%, or 100% I get the desired effect on Texstudio, however other things break.

as a work-around: option/adv. editor/disable cache of rendered lines

@Tim: that is what I see on Linux as well, qimage could fix it ...

[Jan Sundermeyer]

so maybe deactivate the cache on default (maybe except on osx)

[Tim Hoffmann]

disabling the cache seems not to solve the issue.

There's now a development snapshot available using Qt 5.6.1:

https://sourceforge.net/projects/texstudio/files/texstudio/TeXstudio%20development/

Please check if the problem still exists.

hg 6143 (5873d666903c) implements a partial patch:

It works now if you select:
Options -> Advanced Editors -> Workarounds -> Disable cache of rendered lines

Correct rendering while using the line cache is still an open issue.

I think the workaround does not completely solve the problem. On my screen while the editor renders correctly the text in the structure panel is still somehow screwed up. I attached a screenshot for this. Does it only occur on my screen?

Thanks for your help and the workaround!

Hi,

I am facing the same issue although, in this case my laptop and external monitor are both 4K.
I tried to activate the workaround "Disable cache of rendered lines" but this option is grayed out in my program. Do you have any suggestions/tips?

Thanks!!
PS: i use windows 10 and have TeXstudio 2.12.4 (hg 6476:3e5c3afa4719)
Using Qt Version 5.6.2, compiled with Qt 5.6.2 R

Do you use different scalings on the monitors? That would explain it.

To access the settings, you have to uncheck "Try to automatically choose best display options".

[Raul ZM]

Hi Tim,

Using the same scaling in both monitors fixed the issue.
Thanks a lot!!

Do we still need the caching anywhere nowadays? Perhaps we can just disable it by default

I notice no advantage from the caching on linux.

[Jan Sundermeyer]

the slowest renderer, by far, is OSX.
I don't know if the situation is still so disastrous as it used to be, but OSX was the reason to implement a cache in the first place.

[Jan Sundermeyer]

rendering times without cache seem to be okay on older mac book pro with osx 10.13
