I am looking at this from my phone, sorry for this. Is the problem that at the end of the scroll, the background image is shining through?

I wonder if this is only happening on qml branch or also on master. 🤔

No, I am seeing same behaviour on current master as well Contour Terminal Emulator 0.3.11-master-99d6e65a

Ok thx. This was just a hunch.

The problem is that after i insert second image first becomes corrupted and i see this:

Can be reproduced with one image, example julia code f = Figure(resolution=(2000,1100)); ax = Axis(f[1,1]); lines!(ax,rand(100)); f

We figured out that #1458 is only a interim workaround but not an ultimate fix.

What should be done to close this ticket is to probably have a atlas texture size with the dimension of the current screen this window is living in.

• if the window is moved to another screen (or the physical screen size is changed), then the texture atlas needs to be re-allocated
• if the font size is changed only, then the texture atlas itself only needs to be re-addressed and re-initialized but not re-created.
