C++ Builder 10.3.3 rendering issue

 I've installed C++  Builder 10.3.3 few days ago on my secondary PC. Not the newest machine, running Windows 7 64-bit, but still quite capable with quad core CPU and GT430 graphics card. C++ Builder was pretty much useless on it though:

Once new project was created or old project was opened most of the GUI was either frozen or refreshing with  huge delay. At the same time bds.exe was using 100% time of one of the cores. What is weird is that once C++ Builder window width was reduced to about 1100 pixels the problem was gone. Still, working with window width reduced to half of screen width would be very painful.

Solution is easy to find: disable support for themes in IDE (HKEY_CURRENT_USER\Software\Embarcadero\BDS\20.0\Theme\Enabled, set to 0):

Microsoft 5000 series wireless keyboard

 

Model: 1394

X823065-006

March 2014

Lots of screws hidden under stickers and feet.

Rubber palmrest goes first.

Top keypad part is held by latches at each key.

Another semi-hidden screws.

Microsoft X821214-001, LQFP48

25AA01 EEPROM

Nordic 24L01 module

Belinea 101903 LCD monitor

19" LCD monitor

Not working, no obvious problems - so far I gave up.

Max power consumption: 50W on, 4W sleep.

Unusual: front panel is opened by sliding it up.

Panel: AUO M190EN04, made in 2005

4 x CCFL?

Overall less-than-average service friendly design.

TDA7496L - stereo 2W+2W amplifier with DC volume control

3 EEPROM chips

SN74CBT3126 - quad FET bus switch

9435A MOSFET

LM1084 LDO

NCP1203 PWM controller

AP4511GM transistor

BIT3193G PWM controller

2SK2645 600V MOSFET

 

NEC AccuSync 93V LCD monitor

19" LCD monitor from 2008. Working fine, opened to check for possible upcoming problems.

Alternative model name: L195GY

Nominal power consumption: 37W.

STP10NK70ZFP - N-CHANNEL 700V - 0.75Ω - 8.6A - TO220-TO220FP

Zener-Protected SuperMESH™ MOSFET

TSUM1PFR-LF from Mstar

25VF010A SPI Flash, 1Mbit

Easy to open and reassemble, although latches are made from thin plastic and may easily be damaged.

Universal remote controller

 Very cheap "MAXY 1708" universal remote controller bought in 2003.

Devices can be assigned to 6 programmable buttons (TV1, TV2, VCR, etc.).

Main issue: high current draw when idle (45uA) that may lead to premature cells depletion and leakage (for comparison: Sony RM883 consumes only 0.05uA).
