[BUG] MT5 Build 5440 (21 Nov 2025): Critical GUI Rendering Issue in Custom MQL Applications - page 6

New comment
 
Tsvetan Tsvetanov #:

Another bug (build 5464) - the color of OBJ_RECTANGLE is also incorrectly affected by CHART_COLOR_BACKGROUND.

Compare the code example in build 5430 and 5464.

Fixed in 5478 (possibly before but I could not check).

Thanks!  I found new bugs in build 5478 - clrNONE is still not applied correctly to OBJ_BUTTON and OBJ_RECTANGLE_LABEL.  Compare the code in 5430 and 5478.

clrNONE is still not applied correctly to OBJ_BUTTON and OBJ_RECTANGLE_LABEL
Confirmed and reported.
 

5483 bugs fixed in 5484, including missing non-transparent BMP icons.

Everything is stable in 5484 except the fonts I’m using (Inter), which are not rendering properly.

 
Tsvetan Tsvetanov #:

You're welcome.   I have more....

Here is another one -  In build 5430 the trend lines have rounded ends and if you set time0 = time1 and price0 = price1 the trend line will appear as a round dot.

In build 5464 the trend lines have square ends and if you set time0 = time1 and price0=price1 the trend line disappears.

Fixed in 5485.
 
Andrey Barinov #:

Here is all together summorized.


Behaviour in b5430. ALL CORRECT, as expected. Absolutely transparent canvas.


build 5463. Correct only in color scheme Color on White. All other color schemes are wrong...


Fixed in 5485.

Fixed in 5485.

What about the font rendering issue (for example, with the “Inter” font)?
I’m still facing this problem.

What problem ? Please give details.

What problem ? Please give details.

Some fonts (such as "Inter" or "SF Pro") do not render properly and appear empty, as shown in the screenshot I provided (Inter vs Arial).
However, it works correctly when I use native fonts such as Arial.

I can't do anything with screenshots.

For a bug to be fixed it needs to be reproduced, and to be reproduced we need mql5 source code.
