The fact that the display is faded in the second photo, means that there is a supply problem to the display, the fading of the display has nothing to do with the communication to the display.
I hope that the following information maybe of some help to you. The following is for a display of 800x600 with 24 bit colour giving a file size of 1.2MB.
BMP file of 1.2MB read time 2 seconds and render time of 1 second for a total of 3 seconds with DMA this saves 1 second for a total time of...
I am unable to view your Proteus file as it is newer than my version, you should show the circuit as a jpg file.
I have simulated circuits like this before and the normal reason why you are getting the time step to small error is because of floating earths. If you are unable to connect an earth...
It is simple enough to get a schematic from Proteus, simply display the Proteus schematic on the screen, hit Print Scrn on the keyboard and paste into paint and then save as a JPG.
There are a lot of advantages of Tantalum over aluminium electrolytic capacitors such as smaller size, higher frequency response, capacitance stability and low ESR etc, however in your application I expect that a aluminium electrolytic will work just fine.
I have updated my Improved G540 English language software. I have added a fix for the ATtiny13 file not found error and China Core file not found error, improved signed USB drivers, and information on creating your own logic chip test files. The supplemental manual has been updated.

I think that your circuit is not right, for example, the Varistor should not be in series with the AC input to the bridge rectifier but in parallel with it and the diode 8 is the wrong way around.
The subtract routine I posted is the standard PIC 16 bit subtract routine that has been used millions of times before.
Don't forget that the borrow flag is inverted so that the carry flag is zero when there is a borrow and a one when there is no borrow.

If you were to measure the ESR of an electrolytic capacitor you will find that it stays mostly constant up to around 150KHz and then the ESR starts to go down until around 2MHz where it then goes crazy due to inductance effects.
