display issue, when using bitmap (solved)

[bambuko]

I have a bitmap inserted into QCAD file with some peculiar display behaviour.
I have some red lines and circles, plus green dimensions, seemingly displaying properly (image is sent to the back),
but when I hoover mouse over the image:
the lines and dimensions dissapear when the mouse is over bitmap only to appear again when the cursor is away from the bitmap.

Is this normal behaviour, or am I doing something wrong?

Code: Select all

QCAD version: 3.26.4.0
Qt version: 5.14.2
Compiler version: gcc 5.4.0
Build date: Jun  4 2021
Revision: 0bb4334f11f4340e470c4135ae61c076a98f919f

I am using it on either on:
elementary OS or Windows 10 Pro

later edit:
the only way to somewhat mitigate the issue, is to introduce "fade" to the bitmap.
So it is OK for now, but would prefer if possible? to use bitmap without fade.

Put the bitmap on a dedicated layer, send it to the back and lock this bitmap layer. Try it and see if that will work in your favor ...

Put the bitmap on a dedicated layer, etc ...

Thank you,
That's exactly what I did (with the exception of locking the layer)
I will try locking and report back whether it makes any difference.

I can confirm, that locking the layer does indeed solve the problem.
Thank you!
