Is there anyway to increase the size of the icons in the top menu bar in the IDE? I am 70 now and my eyesight needs a wake-up here :)

Not apart from changing the resolution of your screen, or tinkering with the internals, sadly.

Just track down the real program (not the launcher) and override it's DPI scaling.

Beside this question like to be slightly outdated I found a neat solution to this issue.

I've the same problem when running STM32CubeIDE (Eclipse 4.23) under Linux on a 4k screen.

It's described here and seems to work: https://askubuntu.com/questions/777411/eclipse-neon-icon-size-in-ubuntu-16-04-hidpi

​So I've edited the ​/usr/share/applications/stm32cubeide.desktop by adding `GDK_DPI_SCALE=0.5 GDK_SCALE=2` to the line beginning with Exec=....

The full line is now

`​Exec=GDK_DPI_SCALE=0.5 GDK_SCALE=2 stm32cubeide %F`

The difference:

STM32CubeIDE on a 4k screen without any specific GDK settings

The same with modified GDK-settings:

Hope it helps if someone is searching for a solution.

BTW, the often mentioned solution `-Dswt.autoScale=175` or similar does NOT work. It only works on older Eclipse versions (prior 4.8?).
